Crock topper

The giver of a Crock Topper engages in activities that result in a sweaty butt crack, so much so that flavors and aromas are quite developed (as they are in a crock pot). The resulting viscous fluid is then liberally applied to the recipient's penis, usually followed by other sexual activities.

"Honey, can you go for a run so you can give me a crock topper for you to eat for lunch?"
