Place it at the end of a failed answer or forgotten line, then follow with a bruh for the reaction and save a long brain fart for a slower gag that needs more room. For a larger edit, swap in a fart with reverb instead of stacking both.

This short clip is a loud, exaggerated fart burst that stands in for a sudden mental blank, the moment a thought vanishes mid-sentence. It hits with a sudden, rattling blast at full volume and cuts off quickly, leaving no room for subtlety. The effect feels blunt, silly and instantly funny, turning a small slip into a joke everyone recognises at once.
