The act of a man inserting pressurized air in a womans anal cavity then fucking with noisy farts slipping out.
Eric pumped Abbas ass with air then she farted all over his cock, he recieved the greatest fart job since rosie o' donnels fabled 1993 fart job.
A gay sex act in which a man with a gas problem(who farts alot) is being screwed in the ass by his partner and then gives sexual stimulation by farting into his partner's penis.
It's kinda like giving a blowjob, but through your ass instead of through your mouth. So that's why it's called a "fart-job!"
Steve(fucking his partner Jon in the ass): Hey Jon, do you have one coming already?
Jon: Yes! Yes, here comes a BIG one!
*Jon lets out a rather long-lasting, noisy, and pungent-smelling fart*
Steve: Aaaaaahhh! That felt so good!
