Oil Derrick 

You have the woman on the bed face down ass in the air. Then you stand over her with your legs spread and go up and down like an oil derrick.

Man Erik was riding her like an oil derrick. I am surprised he didn't strike oil.

Oil Derrick 

This sexual act involves a blumpkin, or any variation there of, where the receiver of the blowjob is simultaneously chewing tobacco and spitting it freely.

This chick was so nasty last night, she let me oil derrick in her hair.

Rusty Oil Derrick

It's when you have anal sex with someone who has eaten too many Potato Chips and their shit is runny and Oily, then before you cum, you pull it out with oily feces still on it and cum in the air. The feces will shoot in the air resembling a Oil Derick.

Man that girl loved the black oiled cum squirting in the air when I did a Rusty Oil Derrick on her last night!
