Slab Ass

The feeling of numbness in the buttocks that one gets after sitting on a hard/cold surface for too long.

I've got to get up and walk about about a bit. I've got a bad case of slab ass.

An ultimate fucking retard, especially a retarded farmer who performs acts of incest for a living.

Wow!! James is such a slab ass!! What a total douche, he must fuck his cousin.
