The act of sticking one or more fingers into someone's anus (clothed or not) while shouting,"Oil Rigger" in a country accent. Best used when the victim is bending over, walking up stairs, or standing in front of you. The reverse reach around Oil Rigger is also always a challenge.
I definitely penetrated the bootyhole when I gave that dude an Oil Rigger on the escalator.

I gave Jimmy the dirtiest rusty hook after I Oil Rigged his fart box.
