A variation on the blow job in which the man has intercourse with a woman's (or a man's) mouth, grabbing her head and forcing his penis so deep into the receiver's mouth that it goes down the throat, resulting in gagging, choking, and hopefully vomiting on his genitalia. Also, the gagger can voluntarily choke herself on the penis, by thrusting her head back and forth as she attempts to swallow it.
Dude, I'd like nothing more than to make that girl give me a gag job -- just fuck the shit out of her mouth till she barfs all over my cock.

Someone who you fuck although every word out of their mouth is garbage. The metaphor is stuffing a gag in their mouth so you don't have to listen to their nonsense while you bang them. You could be fucking them because you're desperate. You might screw them because, despite being stupid, arrogant or full of themselves, they are extremely physically attractive or sexually skilful. Compare and contrast with 'bag job'.
Tony's a moron, but a great gag job. He ate my pussy and hammered my g-spot all night, but as soon as he opened his mouth I threw him out.

I've got a right gag job tomorrow, will probability do 2 hours work within the 8 hours I'm there and not even have to concentrate much. My mate Sam is always on gag jobs.
