Blowing into a vagina while performing oral sex filling it up like a balloon then pushing down with both hands on the lower abdomen to quickly (and loudly) release the air.
If you really want to see how cool she is you should try popping the balloon of pandemonium
The act of sticking one’s finger into a vagine that just received a creampie in order to release any remaining baby gravy held deep within the love cave.
So Steve, get this, last night I bust a nut in my girl so I helped her out by popping the balloon.
To let out a lot of gas with a fart, relieving pressure in your gut or also to fart, making a noise similar to a rapidly deflating balloon.
Ah man I just love when I deflate the balloon, it always feels so good to deflate a bit.

I just heard someone deflating the balloon, I don't want to go near them.
