Blumpkin's Law 

A situation in which a party is promised a specific result in a situation by another party, and the result fails to occur. In those circumstances, the second party must act out the promised original result.

1) You said that chick would blow me, that's some total Blumpkin's Law right there!

blumpkin steam 

A combination of the cleveland steamer and the blumpkin.
The blumpker, who is giving oral sex allows the blumpkee to stand over the blumpker and release both semen and feces onto their upper body.

I gave my concubine a blumpkin steam when she let me shit on her chest while suckin' me off.

Blumpkin Patch 

Instead of going to pick out Pumpkins, you find someone on the Pumpkin Patch, and convince them to suck your cock while you take a shit on the ground. Around Halloween is the best time to have this very obsene event happen.

Hey Dawg! it's almost Halloween, do you wanna go to the Blumpkin Patch?

Blumpkin'd 

When you post on Facebook and two seconds to one hour later someone posts under it and says they could, would, should, but gotta, work, shave, cry, or they would totally get involved.

Dude! I just posted two seconds ago and fuckin' "so and so" already says they gotta work, shave, cry. Now no one else will touch this post with a ten foot keyboard. Fuckin' blumpkin'd my shit!!!
