Butthole blowback

When someone farts into your butthole and you fart it back out.

That was an impressive butthole blowback, Sally.

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

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?

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!!
