Tayo is the cheerful little bus from the South Korean children's animated series Tayo the Little Bus, and the .EXE label places this clip in the online horror-meme tradition of corrupted, sinister versions of familiar characters. Short distorted laughs like this circulate on soundboards and in short-form edits, where the contrast between a friendly children's character and an unsettling sound does most of the work. Creators keep returning to it because the laugh is instantly recognisable to viewers who know the meme, while still sounding strange enough to unsettle viewers who do not.
