slangCommon Term
Mewing
MYOO-ing
Definition
Pressing your tongue against the roof of your mouth, claimed (without solid evidence) to sharpen your jawline — part of the looksmaxxing world. It also became a gesture meme: a finger over the lips meaning 'shh, I'm mewing, don't make me talk.'
Example Usage
“Don't talk to me, I'm mewing.”
Note for Parents
The gesture is a harmless joke. The underlying idea belongs to the looksmaxxing / appearance-optimisation trend (see Looksmaxxing) — fine in small doses, worth noticing only if it tips into genuine appearance obsession.
