Boss is a 2017 track by American rapper Lil Pump, released on his self-titled debut mixtape and built on sparse, hard-hitting trap production. Its short, chant-like hook made it easy to lift into memes, edits and short-form videos, where the song's boastful tone matched flex and reveal content. As Lil Pump's early breakout material continued to circulate online, the clip stayed in use as a quick shorthand for confidence and success, especially in gaming, sports and lifestyle edits.
