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!?”
