The act of pouring vegetable oil in a girl's anus and pumping it out with your penis. Depending on the girl it might come out a little dirty!
Person 1: I heard you Dirty Oil Rigged Chelsea last night
Person 2: Yeah I struck oil. It made a huge mess and her parents were pissed.

When you are with a partner and you ejaculate into their anus and use the Milwaukee Power Plunger to jam it home.
Did you hear about Jason? He was with a girl and dirty rigged her after getting a rim job and then pounding her in the ass.
