Single Word Request for an adjective to replace my use of the word "gay" to describe [closed]

cringeworthy seems reasonably popular at the moment.

Here is an adjective for the excessively emotional or sentimental behavior:

sappy adjective U.S.

3a: overly sweet or sentimental

3b: lacking in good sense: silly

(Merriam-Webster online)

sappy (adj.) "full of sap," Late Old English sæpig, from sæp (see sap (n.1)). Figurative sense of "foolishly sentimental" (1660s) may have developed from an intermediate sense of "wet, sodden" (late 15c.). Earlier, now obsolete, figurative senses were "full of vitality" (1550s) and "immature" (1620s).

(etymonline)

I would go with "lame," since it seems to me that people use "gay" to describe lame stuff that isn't necessarily sappy.

"Twee" has always been my fallback for just this situation. It has just the right level of contemptuous disdain.

Unfortunately, Merriam-Webster.com says it's chiefly British, so it may not work so well universally:

Twee: adjective \ˈtwē\ : sweet or cute in a way that is silly or sentimental

Chiefly British: affectedly or excessively dainty, delicate, cute, or quaint [such a theme might sound twee or corny — Times Literary Supplement]
