Big Mom is Charlotte Linlin, one of the Four Emperors in Eiichiro Oda's One Piece manga and anime, and her distinctive Mamamama laugh is a classic example of the series giving major characters a unique laugh style. Fans clipped the laugh from anime episodes and shared it on soundboards and in edits, where it became shorthand for a powerful female villain who is amused rather than threatened. It remains popular with One Piece fans because few laughs are so instantly recognisable from just a few seconds of audio.
