Accidentally talking about cocaine. Could also be when you get your hair done. But this definitely this has nothing to do with blowjobs.

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.

Something you say to someone named Johnny, specifically when he denies that his full name is indeed Johnathan. Best said frequently to remind Johnny that he should blow it out his ass.
