Dr. Dong Tip's definitions
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
