A sexual act, popularized by B. F. Skinner, between a woman and a man with
foreskin in which the female ties the man down and locked him
in a box with a
glory hole. The act involves the man sticking his dick through the hole whilst the woman takes some sort of blade and skins the foreskin off.
“Man, it’s my
girlfriend’s birthday today! I forgot to get her a present”
“I guess you’ll
just have to give her the skinnerbox tonight!”
“No, I
already did the skinnerbox last year there’s no more for her to skin off!!”
