Fatal blowback

When the firebox door of a steam locomotive is opened in a tunnel, with the blower on. The action of opening the firebox creates negative pressure in the cab, thus forcing the contents of the firebox into the cab (coal, fire, etc) usually resulting in the deaths of the crew.

Guy 1: did you here how John and Michael died?
Guy 2: no, how?

Blowback

It’s this thing you can get from a chick when they give you a handjob. What happens is, they’re wanking you off, and then just as you’re about to blow your wad, they put their thumb over the end of your knob. If you’re really unlucky, the sperm flies straight back down your tubes and knocks out your spinal column

Hey man, why’d you get that back brace again?

Oh my chick gave me blowback

Status blowback

The negative reaction by an audience to someone who displays or experiences higher status, often as a result of resentment, envy, or jealousy at the person's status.

I don't want to wear my expensive watch to meet that group because of the potential status blowback.

blumpkin blowback

The delicately balanced art of getting your cock sucked while taking a dump, combined with the holy grail of the splash from the dump landing in her eye.

With one big splash and a squeal, my blumpkin turned into a blumpkin blowback, pushing me right over the edge!!

Crusty Blowback

When you're simply too lazy or poor to get more tissue so you pick up some old crusty tissue out the bin to blow your nose on so you don't have to move or buy tissue.

"Hey man you still got that cold?"

"Yeah, I was so tired I had to Crusty Blowback I couldn't be bothered to get more tissue "

OR

"Fuck man I just had a wank and I had nothing to clean with so I had to Crusty Blowback!"
