Cheesy Backseat

Having a container of nacho cheese spilled all over the back seat of your car, after having anal sex when you walk you can hear a smacking sound and your ass is sealed with sperm

Italian Backstache

A rare medical condition in which the sufferer's back is engulfed in a thick, black, musky muff of hair. Usually those afflicted happen to be extremely short and tend to remain virgins well into their forty's. Sometimes affects the torso and genitals, in these cases the condition is referred to as an "Italian Bodystache".

When Tom removed his shirt revealing his Italian Backstache at the community pool, Jefferson grabbed his son and ran fearing a grizzly attack.

Lisa: "Gena, did you hook up with that guy with the green lantern tattoo last night?"
Gena: "I was going to until he took of his shirt. He had a major Italian Bodystache."
