Checking the oil 

When you have so much grease and mold saturating the pubic hairs in the region between your gooch and your innermost cheek, that you can barely walk another step, and therefore "check," the oil. Depending on the circumstances one might: change your yellowing, mud-stained briefs, or dispose of them in the nearest body of water.

Goddamn! It's so hot out here that there is anal waste and sweat running down the bottom side of my thigh out of my shorts! This definitely requires checking the oil

Checking the Oil 

In football when while in the dog pile you grab and twist and/or rip, someone's dick on the opposite team.

I don't know why they're so mad coach all I did was check their oil ( i.e. checking the oil).

Checking the oil 

You delinquently lift up the clitoral hood then proceed to aggressively lick the pussy until she squirts.

I was checking the oil on your mom last night.
