It is a derivative of cankles but much more goliath. It is basically a womans (or mans) figure that starts at their shoulders and goes straight to their feet without any
deviation much like a 2X4 but in this case a 90X90.
guy 2: DAMMMN, those are beyond cankles, those are shankles!!!
I think I've pulled my shankle from rolling my toes so much in marching band.
The winner of the butt kicking contest is the person with the dirtiest shankle.
shorts + ankles = shankles
I bet them shankles do not keep him cool on this hot day.
