Unblumpkin 

Receiving a rimjob while taking a piss.

Blumpkins are fine but don't have to poop. However, I do have to pee so how does an unblumpkin sound?

unfumpkin 

the act of performing cunnilingus while she is defecating. Role reversal for a blumpkin.

I've been dating Betty for a couple weeks now and she asked for an unfumpkin. I was like, "girl there isn't enough mouthwash in the world for that shit."

Sitting on the can and wanna suck your own dick. But you can’t reach it so your start cycling your legs to try and get it closer. While emptying your bowels.

I was looking for a blumpkin but couldn’t find one. so I made my own uniblumpkin.
