Cheater

Cheater (pronounced chee-ter)

(1) A person who cheats.

(2) A device or component used to evade detection of non-compliance with rules or regulations (such as the (Dieselgate) mechanical and electronic devices used by Volkswagen and others to cheat emissions testing programmes (usually as a modifier).

(3) Slang for eyeglasses or spectacles (archaic).

(4) In mechanical repair, an improvised breaker bar made from a length of pipe and a wrench (spanner), usually used to free screws, bolts etc proving difficult to remove with a ratchet or wrench alone; any device created ad-hoc to perform a task not using the approved or designated tools.

1300-1350: From the Middle English cheater from cheat, from cheten, an aphetic variant of acheten & escheten, from the Old French eschetour, escheteur & escheoiter, from the noun; it displaced native Old English beswican.  The -er suffix was from the Middle English –er & -ere, from the Old English -ere, from the Proto-Germanic -ārijaz, probably borrowed from the Latin -ārius.  The adoption was reinforced by the synonymous but unrelated Old French –or & -eor (the Anglo-Norman variant was -our), from the Latin -(ā)tor, from the primitive Indo-European -tōr.  The suffix was added to a person or thing that does an action indicated by the root verb, thereby forming the agent noun.  The noun cheatery is now rare, existing only in old texts.  Escheat refers to the right of a government to take ownership of estate assets or unclaimed property, most often when an individual dies without making a will and with no heirs.  In common law, the theoretical basis of escheat was that (1) all property has a recognized owner and (2) if no claimants to ownership exists or can be identified, ownership reverts to the King (in modern terms the state).  However, in some circumstances escheat rights can also be granted when assets are held to be bona vacantia (unclaimed or lost property).

The original sense was of the "royal officer in charge of the king's escheats," and was a shortened form of escheater, agent noun from escheat.  The meaning “someone dishonest; a dishonest player at a game” emerged in the 1530s as the Middle English chetour, a variant of eschetour following the example of escheat +‎ -er which evolved in English in the modern form cheater (cheat + -er).

Heav'n has no rage, like love to hatred turn'd, nor Hell a fury like a woman scorn'd. William Congreve, The Mourning Bride (1697).

Cheater cars are a frequent sight on several social media platforms, posted presumably by impressed spectators rather than victims or perpetrators.  Techniques and artistry vary but there does seem to be a trend whereby the more expensive the car, the larger and more lurid will be the lettering.  Red, pink and fuchsia appear the colours of choice except where the automotive canvas is red; those artists adorn mostly in black or white.  Hell also hath no fury like a woman cheated upon.

Politicians are notorious liars and cheaters, some even cheerfully admitting it (usually when safely in their well-provided for retirement) but in the privacy of their diaries, they’ll often happily (and usually waspishly) admit it of others.  Although he has a deserved reputation for telling not only lies but big lies, no one has ever disputed Joseph Goebbels’ (1897–1945; Reich Minister of Propaganda 1933 to 1945) assessment of a fellow cabinet member, foreign minister Joachim von Ribbentrop (1893–1946; Minister of Foreign Affairs 1938-1945) of whom he said “He bought his name, married his money and cheated his way into power”.

Guilty as sin.  Oliver Schmidt (b 1969; inmate number 09786-104 in US Federal, York Township, Michigan) received a seven year sentence for his involvement in the Volkswagen Dieselgate scandal.  Herr Schmidt (right) is pictured here receiving a Ward’s “Best Engine” award in 2015.

Volkswagen certainly gave cheating a bad name and in May 2022 the company announced the latest out-of-court settlement would be Stg£ 193 million (US$242 million) to UK regulators, following the Aus$125 million (US$87 million) imposed by the Federal Court of Australia.  To date, Dieselgate has cost the company some US$34 billion and some criminal cases remain afoot.

In simpler, happier times, cheating was sometimes just part of the process and was something of a game between poacher and gamekeeper.  In the 1960s, NASCAR racing in the US was a battle between scrutineers amending their rule-book as cheating was detected and teams scanning the same regulations looking for loopholes and anomalies.  The past master at this cheating was Smokey Yunick (1923–2001), a war-time bomber pilot whose ever-fertile imagination seemed never to lack some imaginative idea that secured some advantage while remaining compliant with the letter of the law (at least according to his interpretation).  His cheats were legion but probably the most celebrated (and there would have been judges who would have agreed this one was legitimate) concerned his interpretation of the term “fuel tank capacity”.  NASCAR specified the maximum quantity of fuel which could be put in a tank but said nothing about the steel fuel line running from tank to engine so Smokey replaced the modest ½ inch (12.5 mm) tube with one 11 feet (3.6 m) long and two inches (50 mm) wide, holding a reputed 5 gallons (19 litres) of gas.  That was his high-tech approach.  Earlier he’d put an inflated basketball into an oversized fuel tank before the car was inspected by scrutineers and when they filled the tank, it would appear to conform to regulations; these days it’d be called “inflategate”.  After passing inspection, Ynuick would deflate the ball, pull it out and top-up his oversized tank for the race.  Pointing out there was nothing in the rules about basketballs didn’t help him but did lead to the rule about a maximum “fuel tank capacity”, hence the later 11 foot-long fuel line.

NASCAR's letter of approval.

Yunick’s 1966 Chevrolet Chevelles were different from the stock models but by the mid 1960s, all NASCAR’s stock cars were.  The difference was certainly perceptible to the naked eye and an urban legend arose that it was a 7:8 (some said 15:16) scale version.  The body’s external dimensions were however those of a stock Chevelle although the body was moved back three inches for better weight distribution, the floor was raised and the underside was smoothed out to improve the aerodynamics.  For the same reason the bumpers were fitted flush with the fenders.  The first car passed inspection (after making the modifications decreed by NASCAR) and took pole position at the 1967 Daytona 500.  Yunick built another imaginative Chevelle for the 1968 race but it never made it past inspection.

Mania

Mania (pronounced mey-nee-uh or meyn-yuh)

(1) Excessive excitement or enthusiasm; craze; excessive or unreasonable desire; insane passion affecting one or many people; fanaticism.

(2) In psychiatry, the condition manic disorder; a combining form of mania (megalomania); extended to mean “enthusiasm, often of an extreme and transient nature,” for that specified by the initial element; characterized by great excitement and occasionally violent behavior; violent derangement of mind; madness; insanity.

(3) In mythology, the consort of Mantus, Etruscan god of the dead and ruler of the underworld.  Perhaps identified with the tenebrous Mater Larum, she should not be confused with the Greek Maniae, goddess of the dead; In Greek mythology Mania was the personification of insanity.

(4) In popular use, any behavior, practice, cultural phenomenon, product etc enjoying a sudden popularity.

1350–1400: From the Middle English mania (madness), from the Latin mania (insanity, madness), from the Ancient Greek μανία (manía) (madness, frenzy; enthusiasm, inspired frenzy; mad passion, fury), from μαίνομαι (maínomai) (I am mad) +‎ -ῐ́ᾱ (-íā).  The –ia suffix was from the Latin -ia and the Ancient Greek -ία (-ía) & -εια (-eia), which form abstract nouns of feminine gender.  It was used when names of countries, diseases, species etc and occasionally collections of stuff.  The Ancient Greek mainesthai (to rage, go mad), mantis (seer) and menos (passion, spirit), were all of uncertain origin but probably related to the primitive Indo-European mnyo-, a suffixed form of the root men- (to think)," with derivatives referring to qualities and states of maenad (mind) or thought.

The sense of a "fad, craze, enthusiasm resembling mania, eager or uncontrollable desire" dates from the 1680s, the use in English in this sense borrowed from the French manie.  In Middle English, mania had sometimes been nativized as manye. The familiar modern use as the second element in compounds expressing particular types of madness emerged in the 1500s (bibliomania 1734, nymphomania, 1775; kleptomania, 1830; narcomania 1887, megalomania, 1890), the origin of this being Medical Latin, in imitation of the Greek, which had a few such compounds (although, despite popular opinion, most were actually post-classical: gynaikomania (women), hippomania (horses) etc).

The adjective maniac was from circa 1600 in the sense of "affected with mania, raving with madness" and was from the fourteenth century French maniaque, from the Late Latin maniacus, from the Ancient Greek maniakos, the Adoption in English another borrowing from French use; from 1727 it came also to mean "pertaining to mania." The noun, "one who is affected with mania, a madman" was noted from 1763, derived from the adjective.  The adjective manic (pertaining to or affected with mania), dates from 1902, the same year the clinical term “manic depressive” appeared in the literature although, perhaps strangely, the condition “manic depression” wasn’t describe until the following year although the symptoms had as early as 1857 been noted as defined as “circular insanity”, from the from French folie circulaire (1854).  It’s now known as bi-polar disorder.  The constructions hypermania & submania are both from the mid-twentieth century.  The adjective maniacal was from the 1670s, firstly in the sense of "affected with mania" and by 1701 "pertaining to or characteristic of a maniac; the form maniacally emerged during the same era.  Mania is quite specific but craving, craze, craziness, enthusiasm, fad, fascination, frenzy, infatuation, lunacy, obsession, passion, rage, aberration, bee, bug, compulsion, delirium, derangement, desire & disorder peacefully co-exist.

Noted manias

Anglomania: An excessive or undue enthusiasm for England and all things English; rarely noted in the Quai D'Orsay.

Anthomania: An extravagant passion for flowers; although it really can’t be proved, the most extreme of these are probably the orchid fanciers.  Those with an extravagant passion for weed are a different sub-set of humanity and are really narcomanics (qv) although there may be some overlap. 

Apimania: A passionate obsession with bees; beekeepers tend to be devoted to their little creatures so among the manias, this one may more than most be a spectrum condition.

Arithmomania: A compulsive desire to count objects and make calculations; noted since 1884, it’s now usually regarded as being within the rubric of obsessive-compulsive disorder (OCD).

Bibliomania: A rage for collecting rare or unusual books.  This has led to crime and there have been famous cases.

Cacodaemomania: The obsessive fixation on the idea that one is inhabited by evil spirits.  To the point where it becomes troublesome it’s apparently rare but there are dramatic cases in the literature, one of the most notorious being Anneliese Michel (1952–1976) who was subject to the rites of exorcism by Roman Catholic priests in the months before she died.  The priests and her parents (who after conventional medical interventions failed, also become convinced the cause of her problems was demonic possession) were convicted of various offences related to her death.  Films based on the events leading up to death have been released including The Exorcism of Emily Rose (2005), Requiem (2006) and Anneliese: The Exorcist Tapes (2011).

Callomania: The obsessive belief in one’s own beauty, even when to all others this is obviously delusional.

Dipsomania: The morbid craving for alcohol; in pre-modern medicine, it was used also to describe the “temporary madness caused by excessive drinking”, the origin of this being Italian (1829) and German (1830) medical literature.

Egomania: An obsessive self-centeredness; it was known since 1825 but use didn’t spike until Freud (and others) made it widely discussed after the 1890s and few terms from the early days of psycho-analysis are better remembered.

Erotomania: Desperate love, a sentimentalism producing morbid feelings.

Flagellomania: An obsessive interest in flogging and/or being flogged, often as one’s single form of sexual expression and thus a manifestation of monomania (qv).  The English Liberal Party politician Robert Bernays (1902-1945), the son of a Church of England vicar, was a flagellomanic whose proclivities were, in the manner of English society at the time, both much discussed and kept secret.  He was also an illustration of the way such fetishes transcend other sexual categories.

Gallomania: An excessive or undue enthusiasm for France and all things French; rarely noted in the British Foreign Office.

Graphomania: A morbid desire to write.  Niccolò Machiavelli (1469-1527; Italian diplomat, philosopher and political advisor of the Renaissance) attributed many of the problems he suffered to his graphomania and he was right, his sufferings because of what he wrote, when it was written and about whom.

Hippomania: An excessive fondness for horses; an affliction which often manifests as the intense and passionate interest in horses developed by some girls who join pony clubs and fall in love.

Hypermania: There’s a definitional dualism to hypermania; it can mean either an extreme example of any mania or, as used by clinicians, specifically (and characterized usually by a mental state with high intensity disorientation and often violent behavior), a severe case of bipolar disorder (the old manic-depression).  The earlier term was hypomania (A manic elation accompanied by quickened perception), one of the earliest (1882) clinical terms from early-modern psychiatry.

Kleptomania: The obsessive desire to steal; in early (1830s) use, the alternative form was cleptomania.  The klepto element was from the Ancient Greek kleptes (thief, a cheater), from kleptein (to steal, act secretly), from the primitive Indo-European klep- (to steal), from the root kel- (to cover, conceal, save) and was cognate with the Latin clepere (to steal, listen secretly to), the Old Prussian au-klipts (hidden), the Old Church Slavonic poklopu (cover, wrapping) and the Gothic hlifan (to steal) & hliftus (thief).  The history of the word kleptomania is of interest also to sociologists in that as early as the mid-nineteenth century, there was controversy about the use by those with the capacity to buy the services of doctors and lawyers were able to minimize or escape the consequences of criminal misbehavior by claiming a psychological motive.  The argument was that the “respectable” classes were afforded the benefit of this defense while the working class were presumed to be inherently criminal and judged accordingly.  The same debate, now also along racial divides, continues today.

Logomania: An obsession with words.  It differs from graphomania (qv) which is an obsession to write; logomania instead is a fascination with words, their meanings and etymologies.

Megalomania: Delusions of greatness; a form of insanity in which the subjects imagine themselves to be great, exalted, or powerful personages.  It was first used in the medical literature in 1866 (from the French mégalomanie) and came to be widely applied to many politicians and potentates the twentieth century.

Micromania:  "A form of mania in which the patient thinks himself, or some part of himself, to be reduced in size", noted first in 1879 and twenty years later used also in reference to insane self-belittling.  In the twentieth century and beyond, micromania was widely used, sometimes humorously, to refer to things as varied as the sudden consumer in interest in small cars to the shrinking size of electronic components.   

Monomania: An insane obsession in regard to a single subject or class of subjects; applied most often in academic, scientific or political matters but can be used about anything where the overriding mental impulses are perverted to a specific delusion or the pursuit of a particular thing.

Morphinomania: A craving for morphine; one of the earliest of the words which noted specific addictions, it dates from 1885 but earlier still there had been morphiomania (1876) and morphinism (1875) from the German Morphiumsucht.  In the medical literature, morphinomaniac & morphiomaniac rapidly became common.

Narcomania: The uncontrollable craving for narcotic drugs and a term which is so nineteenth century, the preferred modern form being variations of "addiction".

Necromania: An obsession to have sexual relations with the bodies of the dead although, perhaps surprisingly, practitioners (those who treat rather than practice the condition) classify many different behaviors which they list under the rubric of necromania, some of the less confronting being a morbid interest in funeral rituals,  morgues, autopsies, and cemeteries.   Those whose hobbies include the study of the architecture of crypts and tombs or the coachwork of funeral hearses might be shocked to find there are psychiatrists who classify them in the same chapters as those who enjoy intimacy with corpses.

Nymphomania: The morbid and uncontrollable sexual desire in women.  Perhaps the most celebrated (and often sought) of the manias, it dates from 1775, in the English translation of Nymphomania, or a Dissertation Concerning the Furor Uterinus (1771) by French doctor Jean Baptiste Louis de Thesacq de Bienville (1726-1813), the construct being the Ancient Greek nymphē (bride, young wife; young lady) + mania.  The actual condition is presumed to have long pre-dated the term.

Onomatomania: One obsessively compelled to respond with a rhyming word to the last word spoken by another (something possible even with orange and silver).  It’s thought to co-exist with other conditions, especially schizophrenia.

Phonomania: An uncontrollable urge to murder; those who suffer this now usually described as the more accessible “homicidal maniac”.  When applied especially to serial killers, the companion condition (just further along the spectrum) is androphonomania which, if properly argued, could be a defense against a charge of mass-murder but counsel would need to be most assiduous in jury selection.

Plutomania: The obsessive pursuit of wealth (and used sometimes in a clinical setting to describe an "imaginary possession of wealth").

Pyromania: A form of insanity marked by a mania for destroying things by fire.  It was used in German in the 1830s and seemed to have captured the imagination of Richard Wagner (1813–1883); the older word for the condition was incendiarism.

Rhinotillexomania: Nose picking. Gross, but a thing which apparently often manifests when young but fades, usually of its own volition or in reaction to the disapprobation of others.

Trichotillomania: The compulsion to pull-out one’s hair.  The companion condition is trichtillophagia which is the compulsive eating of one’s own hair, one of a remarkable number of eating disorders.

Definitional variations in the criteria for mania, DSM-IV & DSM-5

The study and classification of idea of manias had been part of psychiatry almost from its origin as a modern discipline although the wealth of details and fragmentation of nomenclature would come later, the condition first noted “increased busyness”, the manic episodes characterized by Emil Kraepelin (1856-1926; a founding father of psychiatric phenomenology) as those of someone who was “…a stranger to fatigue, his activity goes on day and night; work becomes very easy to him; ideas flow to him.” 

Whatever the advances (and otherwise) in treatment regimes, little has changed in some aspects of the condition.  In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5, 2013), the primary criterion of mania remains “a distinct period of abnormally and persistently elevated, expansive, or irritable mood” and “abnormally and persistently increased goal-directed activity or energy” but did extend duration of the event to qualify for a diagnosis.  In the DSM-IV (1994), the criterion for a manic episode only required “a distinct period of abnormally and persistently elevated, expansive, or irritable mood, lasting at least one week” whereas DSM-5 now requires in addition the presence of “abnormally and persistently increased goal-directed activity or energy”; moreover, these symptoms must not only last at least one week, they must also be “present most of the day, nearly every day.”

The changes certainly affected the practice of the clinician, DSM-5 substantially increasing the complexity associated with the diagnosis and treatment of bipolar disorder, no longer requiring that clinically significant symptoms which may be present should be ignored.  All those years ago, Kraepelin conceptualized manic-depression as a single illness with a continuum of episodic presentations including admixtures of symptoms which have long since been considered opposing polarity.  DSM-5 thus represents an advance with the possibility of improved treatment outcomes because it enables clinicians to diagnose mood episodes and specify the presence of symptoms inconsistent with pure episodes; a major depressive episode with or without mixed features and manic/hypomanic episodes with or without mixed features.

The revisions in DSM-5 also reflect the efforts of the editors over several decades to simplify diagnostic criteria while developing more precise categories of classification.  In the DSM-IV, both bipolar disorder and major depressive disorder were included in one chapter of mood disorders and a “mixed state” was a subtype of bipolar I mania, a diagnosis of a mixed state requiring that criteria for both a manic episode (at least three or four of seven manic symptoms) and a depressive episode (at least five of nine depressive symptoms) were met for at least one week.  In DSM-5, bipolar disorder and depressive disorders have their own chapters, and “mixed state” was removed and replaced with “manic episode with mixed features” and “major depressive disorder with mixed features.”

Solvent

Solvent (pronounced sol-vuhnt)

(1) Able to pay all just debts; meet all financial obligations (ie not insolvent).

(2) Something with the power of dissolving.

(3) A usually liquid substance that dissolves another to form a solution.

(4) Something that solves or explains (archaic).

1620–1630:  From the Middle English solvent, from the French, from the earlier form solver.  Latin root was solventem, accusative singular of solvēns (releasing), present participle of solvō, derived from the construct se (away) +‎ luō (to untie, set free, separate), most usually as solvere (to loosen, to free).  The meaning as applied to financial debts, originally a French form, dates from the 1650s.  As a substance able to dissolve other compounds, use emerged in the 1670s.  Unfortunately, the Czech noun solvence (solvency) was never picked up by English; its adoption would have made the odd clumsy phrase more elegent.  Solvent & insolvent are nouns & adjectives and solvency & insolvency are nouns; the noun plural is solvents.

Solvents and exfoliants.

Although the end result of use should (helpfully) be similar, technically, solvents and exfoliants differ both  in composition and application.  A solvent is a substance capable of dissolving other substances, typically for the purpose of removing them from the surface to which they've become adhered although in science and industry, they're used also for dilution or extraction and in all but some specialized products, they tend to be liquids, whether used in cleaning, manufacturing or chemical processing.  The concoctions are many but the best known solvents include water, alcohol and the acetone familiar to users of nail-polish removers.  Exfoliants are best-known as the commercially packaged substances used to remove dead skin cells on the face, the hope being an improvement in the texture of the skin and thus a more glowing, youthful appearance.  Unlike solvents which dissolve stuff, exfoliants work by the mechanical-chemical process of physically scrubbing or sloughing off the outermost layer of dead skin cells and are packaged variously as scrubs with abrasive particles, brushes, loofahs, or chemical mixes such as alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs).

In praise of Orange Solv.

Orange Solv is a water-soluble solvent marketed as an alternative to the petroleum, chlorinated or glycol-ether mixtures used in heavy duty cleaning and de-greasing.  Applications include grease and tar removal from engines and parts, paint removal from solvent-resistant hard surfaces and it’s widely used commercially to remove chewing gum and stains from industrial carpets.  It’s been adopted by local governments as an additive to high-pressure water systems in the removal of graffiti and one vlogger (influenced presumably by practical experience) endorsed Orange Solve as the preferred solvent to remove the CHEATER signs spray-painted onto cars by vengeful WAGs.  Orange Solve is made from D-Limonene, an extract from the peel of oranges and lemons.  Low in toxicity, it’s pleasant to use, has minimal skin impact and is biodegradable.  Produced using the waste from the citrus industry, it's classified as non-flammable and when diluted with equal parts water, pH is a mildly alkaline 9. After use, there remains a citrus fragrance wafting about which some enjoy and others find intrusive.

Trope

Trope (pronounced trohp)

(1) In art and literature, any literary or rhetorical device, as metaphor, metonymy, synecdoche, and irony, that consists in the use of words in other than their literal sense and which tends to become a motif.

(2) In rhetoric, a figure of speech in which words or phrases are used with a non-literal or figurative meaning, such as a metaphor.

(3) In geometry, a tangent space meeting a quartic surface in a conic or the reciprocal of a node on a surface (archaic).

(4) In music, a short cadence at the end of the melody in some early music; a pair of complementary hexachords in twelve-tone technique.

(5) In the rituals of Judaism, a chanting (cantillation) pattern, or one of the marks that represents it.

(6) In medieval Christianity (and preserved in the rituals of certain factions in Roman Catholicism), either a phrase or verse added to the Mass when sung by a choir or a phrase, sentence, or verse formerly interpolated in a liturgical text to amplify or embellish.

(7) In Athenian philosophy, any of the ten arguments used in scepticism to refute dogmatism.

(8) In Santayanian philosophy, the principle of organization according to which matter moves to form an object during the various stages of its existence.

(9) In metaphysics, a particular instance of a property, as contrasted with a universal.

1525–1535: From the Latin tropus (a figure of speech (in rhetoric)) from the Ancient Greek τρόπος (trópos) (a turn, direction, course, way; manner, fashion; a mode in music; a mode or mood in logic (in rhetoric, "a turn or figure of speech)) and related to τροπή (tropḗ) (solstice; trope; turn) and τρέπειν (trépein) (to turn).  Root was the primitive Indo-European trep (to turn), related also to the Sanskrit trapate (is ashamed, confused, literally "turns away in shame") which Latin picked up trepit (he turns), the Latin adoption in the figurative.  The meaning is now understood as something more diffuse but technically, in rhetoric, a trope was "a figure of speech in which a word or phrase is used in a sense other than the usual definition".  In English, the word is found often in combined form (such as heliotrope) and occurs also in concrete nouns that correspond to abstract nouns ending in -tropy or -tropism.  Trope is a noun & verb, troper, tropist, tropology & tropism are nouns and tropey is an adjective; the noun plural is tropes.

When younger, Lindsay Lohan's signature trope was playing dual roles (The Parent Trap (1998), Freaky Friday (2003) and I Know Who Killed Me (2007).  During her “troubled starlet” phase, she became emblematic of the “downward spiral” trope.  In 2022, she appeared in Falling for Christmas, Netflix's latest take on the "Christmas movie trope".  Although the scripts for tropes have long followed an algorithm, the studios are said now to be using a predictive form of artificial intelligence (AI) to hone the generation of whatever should have the most audience appeal.  The screen-writers (most of whom drive cars and use other products manufactured using processes in which machines substantially have displaced the human labor content) are are unlikely ultimately to succeed in keeping AI out of their profession and, in the medium term, their future may lie in the creation of the quirky and bizarre but in the economy, that's a niche.  For the formulaic stuff (most commercial cinema), the studios are likely to find the AI path "better, cheaper, faster" and the history of US industrial relations suggests these imperatives will prove irresistible.               

The Stage Five Clinger Trope

Most sources cite origin of the Stage 5 Clinger trope as the movie Wedding Crashers (2005) although there are claims it merely popularized the use; without earlier citations however, the trope’s origin appears to be the movie.  As a technical point, a stage one clinger isn’t initially labelled as such, the term applied retrospectively after syndrome is diagnosed.  If men are smart or lucky, they’ll recognize this by stage two but some men are so stupid they don’t realize until stage four.  While in movie there was no discussion of stages other than “5”, by implication five was most extreme and memes soon fleshed out 1-4:

Stage 1 Clinger: She seems fine

First date goes well, she’s attentive, interested, even gets the drinks sometimes and she makes breakfast.  Afterwards, text messages are fun and flirtatious.

Stage 2 Clinger: Hunter and game

The text messages become frequent, the first hint of the lure / engage / trap strategy of the lone hunter.  SMSs start out OK which lulls you into a false sense of security.  Before long, a few messages have been exchanged, most of which have required you to agree with her about innocuous stuff like the weather or today’s traffic.  Then, she’ll suggest a second date and extract a commitment to a specific time/date/place.  That will be soon.       

Stage 3 Clinger: Manoeuvres

Second date not something you’ll wish to repeat.  Bit creepy, how much she knew about you, clearly adept at mining the web.  To escape, you agree to third date while finding pretext to avoid confirming time.  Within hours, text messages become frequent to the point of nuisance.  Check Facebook and you’ll see she’s friended everyone you know.  Ignore SMS and eventually it goes quiet… for about an hour.  Then she phones.  Third date will not be possible to avoid, the illusion you’ll use it to end things still something you convince yourself to believe.  The S3C stage can frequently be the point of no return.  Acquaint yourself with the tale of Julius Caesar (100-44 BC; Roman general and dictator of Rome 49-44 BC) crossing the Rubicon and ponder.      

Stage 4 Clinger: The circling vulture

By stage four, clinging has slurred effortlessly into stalking and S4C is likely to send your mother flowers on her birthday and attempt at avoidance will prompt texting and calling from other phones.  Those who drive are even more of a threat because, where you go, she can follow so you’ll run into her in the most improbable places, and usually she’ll suggest taking advantage of the coincidence by going to lunch, dinner or whatever else might be close.  No matter how studiously you watch the rear-vision mirror, she’ll hunt you down and find you. 

Stage 5 Clinger: Thrill of the kill

At this point, her life is scheduled around your own, even to the point where she may now work in the same building, expects to have lunch together every day and a drink after work whenever possible.  When you try to avoid these, emotional meltdowns ensue, the only way to avoid a scene being to agree.  Many of your friends start asking you out as a couple and tell you you’re lucky because she’s wonderful.  She’s been to their dinner parties where she talks about your plans together.  Stage five clinger can also be APC ("actual psycho-chick", the two not synonymous but there’s frequent overlap).  Pursuing another relationship in an attempt to dissuade her brings its own problems, the S5C-APC will spray-paint CHEATER on either their car or yours (in red; unless car is red, then she’ll use black).  At this point, faking your own death begins to look like good tactic.

Crooked Hillary (b 1947) and Bill Clinton (b 1946) in the rain at the formal dedication of the William J Clinton Presidential Center, Little Rock, Arkansas, November 2004.  Cling on and no matter what, never let go.

The significance of dividing the path of the clinger into stages is it’s vital to extricate yourself from their clutches during the earliest stage possible; it needs to be remembered progression can be rapid, some clingers so adept at the art they're able to skip one or even two stages.  The longer delayed the excision, the harder it becomes and if allowed to reach the later stages, you may be stuck with her forever and for that, you can’t blame her: you're trapped and it's all your fault; you have only yourself to blame.
