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

before a male has any physical penal or oral contact with "strange" vagina, he must first "check the oil". a simple dip of the finger with a discreet sniff, sniff will do. if the oil needs changing the test finger should be jammed into the female's nostril. if not, have at it, til its done swoll.

When preforming the sexual act of "the shocker", after you insert the "stink finger" you lick it off, as to "check the oil"
