Cock Balloons are like condoms, but cooler. They bring joy and stop icky-ness, like Obama, only not so religious. Often used as a hip way to encourage safe sex.
After sex you pass out with a condom still on. You forget about the condom then go to take a piss. Then rubber fills up with hot nasty post-sex piss. Now you've got a very dangerous situation on your hands
Jane: Whats this mess all over the bathroom floor?
n; whilst engaging in foreplay, the state of the malepenis when it is fully prepared for penetration. Symptoms of this state are usually big, red/purple, throbbing, uncontrollable penises.
"Randy, I think we should skip the forplay, you've got yourself a cock baloon!"
A guy who is so blind to see whats in front of him - when a girl is there wanting sexual pleasure - he takes the condom blows it stupidly as if it was a balloon.
"Karl why do you gotta be such a cockballoon bro? That chick wanted the D in the V so bad but you turned it loose you ass-hat !"
The pocket of air that can form over the tip of your penis when you do not put on your condom correctly. A cockballoon can break easily and make wearing a condom pointless.
