water balloon

You're fucking a girl with a condom, when you blow your wad in it take it off and smack her with it. Thus pissing her off but giving yourself a very good laugh.

Oh my god i got brittany with a water balloon last night.

Salmon Balloon

When someone puts their lips up to a vagina and fills it with air as if blowing up a balloon. You can then take the labia betwixt your forefinger and thumb at the top and the bottom of the vaginal opening to control the amount of airflow on the way out. Moving your hands away from each other while still holding the labia will restrict airflow and cause a high-pitched squeal, and bringing them close together will cause a low-pitched almost flatuesque noise. It is not advised to let go of the labia before the vagina has equalized air pressure with the outside atmosphere because there is a risk of the woman flying around the room and injuring herself or others in the process. An advanced knowledge of rocket science is needed to explain this phenomenon.

Did you hear Katie is in the hospital? Aparantly there was a pretty serious accident when she got a salmon balloon from Ben.

Green Ballooned

To be punched, choked and slapped around, etc. during rough sex while the dominant partner ignores your pleas to stop. MO Speaker Rod Jetton was accused of assault and battery of a woman one night after his divorce. He later said it was her fault that she was beaten without her consent because she didn't use the safe word, "Green Balloons".

"Lucy got green ballooned last night after an S and M sexcapade gone wrong."

John: "Dude, what happened Eric? You look all beat up."
Eric: "Yeah, Emily green ballooned me. I'm pressing charges on that bitch."

Convertible Balloon Syndrome

After listening to Wavves' "King Of The Beach" album, I discovered I hated the song "Convertible Balloon." I had to delete it, but for some strange reason, I couldn't. This is when I discovered I had Convertible Balloon Syndrome. Now I can't just put a few songs from an album on my iPod, I have to have the entire album. It seems to be contagious because I have spread it to a friend. If you think you may have the godawful disease, you share my pain.

I can't delete that song because I have Convertible Balloon Syndrome.
