Lilo

Lilo (pronounced lahy-loh)

(1) The trademark for a type of inflatable plastic or rubber mattress, often used when in lakes, swimming pools etc.

(2) As a generic term, any inflatable mattress, especially those used recreationally in lakes, swimming pools etc).

(3) The portmanteau slang synonym for Li(ndsay) Lo(han); it was also applied as the name of a dance Ms Lohan performed ad-hoc on the Greek island of Mykonos in 2018.

(4) As LILO, the acronym for Li(nux) Lo(ader), an early (1991-2015) boot loader for the Linux operating system.

(5) As LILO, in computing, organizational management, accountancy and behavioral science, as the acronym for L(ast) I(n), L(ast) O(ut), a companion unit descriptor to FIFO (First In, First Out) & FILO (First in Last Out), all methods with which to organize the manipulation of data structures.  Under LILO, the last object in a queue is the last object to leave the queue.

1944: The trademark name Lilo (originally Li-Lo) registered by the company which made inflatable air-mattresses of rubberized canvas dates from the 1940s (1944 in the UK; 1947 in the US) and was a sensational spelling based on the phonetic “lie low”.  Lilo also exists in other languages: In the Philippines, in the Cebuano language a lilo is a swirling body of water or a large and violent whirlpool (a maelstrom) while in Tagalog it’s an adjective meaning disloyal; unfaithful; traitorous; treacherous (the synonyms being taksil, sukab, mapagkanulo & traydor).  In Hawaiian, Lilo is a feminine given name meaning “generous one” although in some traditions in the islands it can be translated as “lost” so the song He Mele No Lilo translates (loosely) as “Lullaby of the Lost”.  Lilo is a noun, the noun plural is lilos.

The Li-Lo Kayak, 1960.  The car depicted is a stylized rendition of an early version of one from the Rootes Group's "Audax" range (1956–1967).

The technology of the lilo was adaptable and able to assume various shapes, the LiLo company dabbling in a number of market niches including furniture, packaging and inflatable canoes.  The Kayak however was complex in construction so its production was thus labor intensive so it never sold in the numbers required to achieve the economies of scale which could have lowered the price and at Stg£25 (over Stg£500 in 2022 values) it was too expensive to succeed.  The idea has however been revived in the twenty-first century and "lilo & inflatable kayak" adventure tourism is now a thing.

The Bravissimo Lilo

The joke which buyers took seriously: the Bravissimo Lilo.

Bravissimo's Lilo appeared originally in 2018 as an April Fools' prank but such was the demand it was put into production and is now Bravissimo part-number SW571, available exclusively in hot pink.  Although there have since the 1940s been improvements in materials (lilos are made usually from polyvinyl chloride (PVC) or textile-reinforced urethane plastic or rubber), the innovation on Bravissimo's is the first structural change in design in seventy-five years.  Integrating what the manufacturer calls “cup holders” the unique feature is a one-size-fits-all lacuna at the appropriate position so the breasts may comfortably rest un-squished when a woman is supine, lying face-down

Room to move: One size fits all.

Even Bravissimo, an underwear company which specializes in the niche of bigger boobs, admits they really should have thought of this before, given the discomfort suffered by lilo-using women tends to increase in direct proportion to cup-size.  It’s available in-store in some Bravissimo outlets and on-line at Stg£28 (US$45).

No longer one size fits all: Crash test dummies (CTD) now more inclusive.

Perhaps Bravissimo being nudged into making available a lilo which took account of women's unique anatomical differences inspired others because, some fifty years after they came into use, Swedish engineers have at last developed a crash-test dummy (CTD; "seat evaluation tool" the technical term) representative of the body of a typical woman.  Until now, almost all CTDs have been based on the build and weight of a typical adult male.  In most markets however, women however have long represented about half of all drivers and passengers yet the CTD manufacturers and regulators used in testing as a proxy for women was a scaled-down version of the male one, roughly the size of a typical girl of twelve and at 1.49m (4', 8") and weighing 48kg (106 lb), in accord with only the smallest 5% of women by the standards of the mid-1970s.  The new CTD is a more representative 1.62 m (5', 3") tall, weighing in at 62kg (137 lb) so it's another DEI (diversity, equity and inclusion) building block. 

The need for a range of CTD with characteristics covering most of the population was discussed in the 1960s when US regulators began to write the first standards for automotive safety but industry lobbyists did their work and ensured crash-testing would be done as cheaply as possible, hence the standard, one-size-fits-all male analogue.  Despite years of convincing research which confirmed women were disproportionately injured in crashes (height rather than weight apparently the critical variable in the interaction of their smaller frames with seat-belts and air-bags), it wasn't until 2011 that US federal regulators required manufacturers to use more petite CTDs in frontal automotive crash tests.  It's hoped the new, Swedish-developed CTD will improve outcomes and the data from physical testing will soon be available for use in the increasingly important computer emulations, a field in which artificial intelligence (AI) is proving useful.

Lindsay Lohan: Studies of Lilo lying low in three aspects.

Lindsay Lohan’s moniker LiLo is a blend, the construct being Li(ndsay) + Lo(han).  Being based on proper nouns, in linguistics this would by most be regarded a pure blend, although some would list it as a portmanteau which is a special type of blend in which parts of multiple words are combined into a new word (and some insist that in true portmanteaus there must be some relationship between the source words and the result).
