Truffle cream

The cream that comes from having anal sex, pulling out your penis and rapidly rubbing it through the crack.

Backseat cabbage

When you're having sex in a car in the front seat and when the guy gets off he catches it in his hand and throws it in the backseat so no one has to sit in the wet spot.

Yeah I'll give you a ride. Just if you don't mind the backseat cabbage we'll throw a blanket over it or something
