the part of a womans ass that hangs out of her home made jean shorts. the part that is the lower inside portion of the ass cheek just above the crease.
I'd love a piece of the keister cake on that thing.
She said, " can you see my Keister Cakes in these home made jean shorts".
I hope I can find someone serving up some home made Keister Cakes at the county fair.
Damn girl i didnt know you were selling Keister Cakes.
