Butterfly was released in 1998 by Swedish Eurodance group Smile.dk and became widely known outside Europe after it was included in the Dance Dance Revolution arcade games. Its simple repeated chorus and fast tempo made it easy to remember and easy to sample. Decades later short clips of the ai yai yai hook resurfaced on TikTok and in anime edits, where creators loop the most recognisable seconds rather than the full track. That second wave turned a late nineties dance song into a familiar meme sound.
