Rear cleavage

Another way of referring to someone's ass crack that's hanging out. Hence the "rear" in the term.

Same as saying "butt cleavage."

*guy walks by with his ass crack showing due to his pants being down too low*

Person 1: "Whoa, that guy's got some major rear cleavage there!"

Person 2: "I know. That's kinda... gross."

1) A raised flat portion of a sedan or coupe that is usually located behind the second row of seats. The rear shelf is on the same level as the trunk of a car making items placed upon them visible through the vehicle's rear window.

2) Someone with such a huge fat ass that you can place items on, for instance the entire Encyclopedia Britannica.

Dear god! Why won't the rear shelf stop making noise? Please kill me now.
