The cleavage of the lower buttock area. Butt + Cleavage = Bleevage
(Not to be confused with the term "butt crack," which is the cleavage of the upper buttock)

The girl wearing daisy dukes was showing bleevage.

bleavage 

A contraction of "back cleavage." Often occurs when a fat woman wears a tight bra, tank top or other garment that shows off the back area, thus squishing the back fat together to give the illusion of cleavage on their back.

That tank top is giving that girl some serious bleavage.
