Place it at the very end of a short edit as the final reply, after the setup line finishes. Follow a failed attempt with the bruh sound first, then let this clip close the scene, or pair it after an emotional damage sound for a defiant answer.
About this sound
This is a very short voice clip of Bart Simpson delivering his catchphrase 'Eat my shorts' in a cheeky, defiant tone. It lasts just over a second and lands as a playful brush-off, funny because it sounds rebellious and dismissive without being serious. The line comes from the animated series The Simpsons, where it became Bart's signature comeback.
