This version is best understood as a meme edit of a fart sound rather than a quote from a specific film, show, or character. The added spacious effect gives the joke a more dramatic, absurd finish, which fits short-form reaction editing well. Sounds like this spread through meme pages, group chats, and quick-cut videos where creators exaggerate embarrassment, confusion, or mental shutdowns. It stays useful because the basic setup is universal, and related variants like fart with reverb and Long brain fart cover both short punchlines and extended bits.
