Having a pimple so large on your ball sack that it appears to be a third yellow ball. The surface tension is so tight that very little pressure creates a yellow eruption of ball puss.
Last time Longinus needed me to pop his yellow sack,I got a fowl sour yellow explosion all over my face and I nearly passed out due to the smell

The act of being completely naked while thrusting so hard that your balls sack starts smacking against your taint hard enough to make a clapping sound. It is quite and impressive party trick might I add.
Yesterday, my mom caught me doing the sack clack and she started to join in and she was really good at it!

While rodeoing and an injury to the scrotum sack had occurred (tearing a hole in the sack). One states (lies) the injury was to the inner thigh, not the actual scrotum.
“Did you hear about Shannon's bull ride last night?!” I heard he got gored!”
“Where?”
“The inner thigh”.
“Yeah right?! He prolly has a Skiled Sack!?”

This is simply when you expose the hairy flesh that covers your testicles. Usually used to scare or freak out you friends. Oftenly get called a faggot for it.
Jim: Dont go over there Dan is sack-skinning everyone again.
Joe: Oh wow he's such a faggot.
