The joke comes from Bad to the Bone, the 1982 blues rock track by George Thorogood and the Destroyers that became a shorthand for movie tough guys and rebels.

The longer parody version spread through meme edits and soundboards because it lets creators borrow that classic cool guy energy and immediately undercut it for comedy.
