When having sex with an amputee, the man pulls out and nuts all over the stump. A loud yell is also considered appropriate.
Opposable thumbs are usually a criteria for banging a chick, but I really wanted to spunk-a-stump.
That girl missing her arm was a 0 until my 10th Schiltz, but then I took her home and spunkastump-ed her like 3 times that night.
I think that hood rat torso chick is a 0 but I would still spunk all four stumps.
