hand crotch
The skin between your thumb and pointer finger is your hand crotch.
My hand crotch is hurting so bad!
Katie Crotch-Hands
Someone who warms her hands up by sticking them between her legs. It is unknown wither or not she gets sexual pleasure from this.
So we are sitting at Montana's Restaurant, eating dinner, when Katie Crotch-Hands sticks her hands between her legs, in front of everybody! She says "Shut up my hands are cold!"
