Mewing became a widespread online joke and trend on TikTok, where creators filmed themselves pressing their tongue to the roof of their mouth to emphasise their jawline, often as part of looksmaxxing and self-improvement humour. The phrase turned the normally silent technique into a loud, ironic boast, which fit short reaction videos and edits perfectly. Clips like this spread because they are instantly recognisable to viewers who already know the trend, and they continue to be reused for confident, tongue-in-cheek moments in memes and short-form videos.
