The long brain fart became popular in meme editing as an exaggerated alternative to a short fart cue, with the joke built entirely around duration rather than volume. Clips like this circulate on soundboards alongside a fart with reverb and other stretched gag effects, and are shared as reaction audio for streams, edits and group chats. Because no single film or show is credited as the source, its identity comes from repeated online use, where the extended sputter signals a mind going blank in the most literal, ridiculous way possible.
