mew
Pseudoscientific tongue-on-the-roof-of-the-mouth posture, sold on TikTok as a free jawline upgrade.
Definitions
Resting your tongue flat against the roof of your mouth, supposedly to reshape your jaw and sharpen your cheekbones over time. The signature move of looksmaxxing TikTok. Whether it actually does anything is heavily disputed; whether teens believe it does is not.
The TikTok-meme gesture — finger to lips meaning 'I can't speak, I'm mewing' — used as a joke way to dodge a question or stay silent.
mew In A Sentence
Origin & Usage
Named after British orthodontists John and Mike Mew, whose 'orthotropics' theories went viral on TikTok around 2019 and detonated again in 2023–2024 inside the looksmaxxing subculture. Mainstream dentistry considers the jaw-reshaping claims unproven.
