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!

A sexual encounter, usually a gay man, who had just been cummed in, than sharts out their partners cum.

when the male tries to delay an orgasm, and does not realize that he is also retaining some back-gas... When he finally reaches an orgasm, a series of farts and ejaculations become released simultaneously.
Example one: cum fart: did u hear about the time Myra was fornicating with Kenny when he suddenly came and farted at the same time,
Exapmle Two: Damn, I just came and farted at the same time. I swea, that never happened before' That was some serious cumfart!!

After receiving a load of sperm in the rectum, the receiver farts out the juice which is then orally ingested by either parties or a third party.

its when the guy does the girl up ass, and blows it up there, after she is bleeding, she farts, and the cum comes bubbling out all red from the blood
