When you are letting out a long and fulfilling fart, but suddenly, midway through the fart, it changes tune and maybe becomes shrill, bass or downright throaty.
Bro 1: Bro I ate a huge bowl of stale taco shells last night while watching Dazed and Confused and let rip a long fart. But midway through the fart, it screeched and then as I clenched by butt, it changed to a wet fart noise.
Bro 2: Weird shit bro!
Bro 1: Nah bro. It was just a switchfart.
