When a girl orgasms so forcefully that the hydraulic pressure of her ejaculations renders you unable to maintain penetration. The girl herself is a gusher.
I would have stayed over, but when she got off we had a blow-out which knocked me to the floor. So I just put on my pants and left.

A blow out is when you have a soft serve ice cream bowel movement and whether its an hour or 5 mins after the dump , you think its gonna be a clean fart and poof there is the small splatter left over onto your underwear, Not to be confused with the Shart a blow out is not as runny.
Hey man, I ate a whole pot of beans and man I had a nice long dump then I was watching George Lopez and hey bro I thought I had to fart but I had a "blow out"

Occurs when after not shitting for 2 or 3 days, someone mentions poop, and you just lose your bowels.
I was on this date with that girl, and she mentioned how shitty this girl was acting towards her. And while I listened to her, I had a total blowout in my pants. Good thing she is a fecalfeliac.
