Place it at the end of a short blame joke, just after a denial, then follow it with Bruh for the reaction. When the same gag needs a second beat, bring in Fart With Reverb after it, and save Long Brain Fart for the next gag in the same edit.
About this sound
This is a very short fart sound, lasting under a second, with a small, quick burst that fits its tiny name. It feels cheeky and instantly funny, the kind of noise that makes people laugh and point at each other. It works best as a blame-shifting gag, aimed at the friend sitting next to you.
