Carcass Fart 

Inhuman, room clearing, lingering fart. So impossibly bad that it gets WORSE when it diffuses as the pure form is just sensory overload and smells like burning nerve cells. A more horrible expression of "Something crawled up your ass and died.... Weeks ago"

Oh dear God Dan ripped a Carcass Fart. Christ Danny it smells like there's something rotting in your ass!

Carcase Fart

After performing anal penetration with a (recent) corpse (provided the body is still warm), the carcase releases gas from its bowels.

Justin: Hey Matt, I totally just fucked your mom's body after I killed her!
Matt: Oh yeah?
Justin: Yeah dude it was good. Except she totally carcase farted all over my schlong.
Matt: That's probably from the volcano taco she just ate.
