A trick done using your ball sack.

Great in the dressing room or at a party in front of the guys.
Let your sack skin hang out from your fingers and blow on your thumb...gradually releasing a nut into your palm. Making it as if you're blowing up you sack.

Dude, let's balloon her. You wack on the back of the head, and I'll pull out.

Alfred Lord Hymenson once said: "'Tis better to have ballooned and laughed than never to have ballooned a gal."
