All Star is a 1999 song by Smash Mouth that became closely linked with Shrek after featuring in the 2001 film, and its instantly recognisable chorus has made it a lasting meme staple. Fan-made reversed and inverted edits later circulated on soundboards and video platforms, turning a feel-good anthem into something deliberately weird. Because almost everyone recognises the original melody even when it is played backwards, the inverted version works as an instant in-joke, and it remains popular for parody edits, cursed compilations and ironic nostalgia.
