The chant comes from Shots, the 2009 party track by American duo LMFAO featuring Lil Jon, built around a simple call-and-response hook that is easy to shout in a crowd. It first spread through clubs and house parties, where DJs used it to mark a toast or a peak moment in a set. As short-form video grew, creators clipped the repeating hook for party montages, drinking challenges and celebration edits, keeping it alive long after its chart run. Its appeal is its simplicity: anyone can join in instantly, so it still works as shorthand for a night out.
