Sexy and I Know It was released by LMFAO in 2011 as a single from their album Sorry for Party Rocking, and it quickly became a club and party staple thanks to its chantable chorus. The line lived on through dance videos, sports celebrations and parody edits long after its chart run, before short-form video gave it a second life as a shorthand for overconfidence. Creators still reach for it because the phrase needs no setup, and its swagger instantly frames whoever is on screen as the main character.
