Glout

Glout (pronounced glout or gloot)

(1) To scowl or frown (archaic).

(2) To stare gloatingly (obsolete).

(3) To look sullen (modern revival for selfies & memes).

1400–1450: The origin is in late Middle English and although of uncertain origin, it’s related to the earlier use where to glout was “gloatingly to stare”.  The root, the Middle English glouten (to scowl) is thought derived from the Old Norse goltta (scornfully to grin) but, although likely, the link is undocumented.   A verb used without object, the third-person singular is glout; the simple present is glouts, the present participle is glouting, the simple past and past participle is glouted).

Although described as archaic as long ago as the eighteenth century, glout enjoyed a bit of a (brief) early twenty-first century revival as a descriptor of selfies and memes although the more evocative resting bitch face (RBF) tended to be preferred.  In the way the social works, glout soon faded from use.
