The joke builds on The Simpsons, the long-running animated series centred on Homer Simpson and his son Bart, and on Who Let the Dogs Out, the 2000 hit by Baha Men that became a stadium and meme staple. Swapping dogs for Barts turns the chant into a Simpsons pun that needs no context beyond those two references. This version circulates as a very short, voice-altered soundboard clip, shared for edits and reaction videos where the recognisable setup can do the work in under a second.
