When one man ejaculates presumably in another males bootyhole, the other man then begins farting until it spews out like a volcano. At this point he does a backbend letting it leak out into a bowl pre filled with his favorite cereal and then eats it as a desert.
A stinky fart you get caused by cum you got in your ass via anal sex. Unless your some weird fucker who enjoys sticking syringe tubes up your ass with random peoples cum... in which in case; have fun with that!
*Lets out a wet sounding fart.*
"Dude I think you gave me the cum farts."
