check the oil

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

Man, she was so gross but I checked her oil anyways

check the oil

before a female has any physical contact with "strange" wang, she must first "check the oil". a simple dip of the finger with a discreet sniff will do. if the oil needs changing the test finger should be jammed into the male's ass. if not, have at it, til you're satisfied.

Checking her oil

A test to be preformed on a chick before eating her out. Finger her a bit and catch a whiff of your finger and you'll know if its safe to proceed.

Use your finger like a dipstick to check her oil
