Blowback

It is when someone (more than likely a male), takes it in the butt and whoever is on the giving end deposits some semen. the "blow back" occurs when the receipient farts it back out on to the "giver". Hence the term "Blow Back"

I was with my "life partner" going hot and heavy and decided to leave him a gift, he decided to take my "gift" and Blowback on me.

BlowBack

The end result of gassy crap on the back of a toilet bowl.

For example, you go out and eat mexican food chasing it down with the few beers. You wake up the next morning and go to bathroom. The gassy build blows crap on the back part of the toilet bowl called BlowBack.

Martha sucked on Ron's dick until he spewed his jiz into her fucking mouth. Martha then spit the hot load into Ron's mouth as he smiled with glee. It was Ron and Marthas first Boise Blowback, the first of many.

blowback

When someone is performing a blowjob on you, and just as you're about to cum, they put their thumb over the end of your dick. This causes the cum to shoot back into you, usually straight into your spinal column and crippling you for life.

Person A: How did you become disabled?

Guy in wheelchair: I was having sex with a hooker but she did a blowback on me so she could steal my wallet.

Person A: LOL!
