Undersack

The underside of a man's ball sack.

Her tongue gently caressed his undersack as it moved back towards his taint.

Unbefuckenlievable

When something is beyond unbelievable, it is unbefuckenlievable.

1. When Obama became President, it was unbefuckenlievable how stupid people could be.

2. I had pocket Aces and some donkey went all-in pre-flop on QK offsuit and flopped trip Queens. It was unbefuckenlievable.
