This sound comes from the chorus of 'Na Na Hey Hey Kiss Him Goodbye,' a 1969 hit by the band Steam. Over time, the chant moved far beyond radio and became a staple at sports events, where crowds sing it to taunt the losing side or mark a departure. Online, that same chorus turned into a reliable meme audio for dismissals, exits and comedic goodbyes. Its simple melody and instantly understood message are why the clip still shows up in short edits and reaction posts.
