Bonetrousle is a track from Toby Fox's 2015 game Undertale and is widely recognized as Papyrus's theme. The song became popular well beyond the game through animations, remixes, memes and character edits on video platforms. Its bright, jittery energy makes it easy shorthand for over-the-top confidence and lovable chaos, which is why creators still use short cuts of it years later. Even brief clips are instantly familiar to many players and fit comedy edits without needing much setup.
