The act of burping into a girl's vag while proforming oral sex. Her uterous then expands to an enormous size causing her great pain. This often happens when the male has eaten KFC causing him to increase his burping frequency.
"Fuck, my boyfriend gave me a hard core ballooning and it hurt like no other."

What were you doing the other day, Curtis? "Oh I was just ballooning some whore."

(v) The act of pulling one's penis out of a girl's rectum while she is unconscious, thus causing her rectum to be extracted, inside-out, from her body, through her anus. This is a common college party prank.
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."

Anus. Origin of the term Balloon Knot came from Opie & Anthony. A Radio show in NYC. They used the term as a code word for the Anus so they can say it on the radio. BaLLooN NoT is a Devoted Listener to the show and a true Mets Fan.

If the balloon doesn't fit, you may have to do research on how to find the right size.

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.

This is a called "the balloon"
