YYDS (永远的神)

A phonetic, essentially meaningless meme sound ('Hajimi') that can mean a cat (especially a cute orange one), cuteness or playful chaos, an all-purpose nonsense exclamation, or genuinely nothing — its power being that it doesn't insist on a meaning.

'Nonsense literature' / 'empty-talk literature' — a style of online writing built from statements that are grammatically perfect and confident in tone but completely empty of information, looping back on themselves or stating the obvious as if revealing a deep truth.

Smells good / So good — used when someone ends up loving something they previously said they'd never do.

High EQ — being tactful, diplomatic, or knowing exactly the right thing to say.
