o.k.! ass cleavage is defined by how deep a girls ass crack is set within her gluteous muscles. in other words if you took a ruler and stuck it in between a girls ass muscles till it stops at her crack you would have an ass cleavage measurement. how deep a womans ass crack measurement yeilds, is what is known as ass cleavage! ass cleavage is a phrase normally utilized with girls who are very athletically built!

The act of a girl wearing a bikini bottom that is too small. So small to the point that her butt cheeks get pushed together and there is not enough material to cover the top of her butt thus creating ass cleavage.
Wow look at the ass cleavage on her.
