The phrase is best known from Boom Bye Bye, the controversial 1992 dancehall track by Jamaican artist Buju Banton, where batty bwoy is Jamaican Patois slang. Shortened and respelled as batty boi, the chant later circulated far beyond dancehall as a soundboard and meme clip in gaming, chat and short video edits. Stripped of its original context in most reposts, it is now mainly heard as an exaggerated goodbye or elimination cue, reused because the rhythm is instantly recognisable and the delivery fits quick, disposable joke edits.
