The Jamaican vernacular which means "to cheat on your male significant other". (To cheat on your man, boyfriend, husband, fiance etc)
Girl: "He wasn't treating me good, so mi bun him!"
This phrase was made even more popular by the song "Bun Him'" by Jamaican dancehall artistes Macka Diamond and Blacker. The song speaks about a female who complains that her significant other is ill-treating her and cheating on her, to which her friend responds by encouraging her to 'bun him' (cheat on him)
