Definition

Mewing takes the surname of British orthodontist John Mew. On social media it became a jawline tutorial: tongue up, teeth together, nasal breathing. There is clinical debate about what the posture does in adults. There is no debate about what the meme does: it turns the side profile into a project.

Origin

A method associated with John and Mike Mew; YouTube and TikTok popularise the gerund mewing.

History

Once an orthotropics niche, then a teen challenge with a camera timer.

How it emerged

A family name became a facial-grind verb.
