Mewing became a huge online trend as creators posted tongue-posture and jawline transformation videos, and the joke quickly grew bigger than the technique itself. Short edits began pairing intense profile shots with goofy, exaggerated audio to mock the hype around a chiseled jaw, and the format spread across TikTok and Reels. It remains popular because it works as instant shorthand for self-improvement satire, letting viewers recognise the parody in seconds without needing any explanation.
