M to the B is a track by British artist Millie B, originally released as a drill diss track before finding a second life on TikTok in 2020, where the hook became a viral sound for transitions and lip-syncs. Its short, repeatable chorus made it easy to reuse across thousands of short videos, helping the song chart again years after its first release. The clip remains popular because the phrase is instantly recognisable even without context, giving creators a quick musical shorthand for confidence and attitude.
