blowback

1. The expulsion of anal pear and accompanying detritus during gargantuan anal orgasm.

"Walt screamed in horror and ecstacy as his anus erupted in orgasm. Without warning, the nose cone-shaped dildo exploded into the air and struck Juanita directly in her left eye, horribly blinding it forever. It was another tragic case of blowback."

blowback

When you have to hold in a fart due to being in a public or enclosed space (airplane, subway, car) and the fart rumbles back up into your plumbing. Over the course of several hours, a serious queue of un-expelled farts will build up, prompting an extended cropdusting at the earliest convenience.

Joey: Dude, that 8hour flight from Frankfurt was murder. I musta had about 40 blowbacks.

Chandler: Ouch. How'd you eventually clear the backlog?

Joey: I waited till there was nobody behind me on the slidewalk, and did about 300 feet of cropdusting!

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"

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.

Boise Blowback

After performing oral sex on a male to completion, the act of spitting the semen into the mouth of the one who ejaculated.

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.
