Blump Crain 

To give head while taking a shit.
To have oral sex while pooping.
Relieving yourself while getting blown

"Hey brian, that girl sure gives some good blump crain."

Blump Crain by Dave Armstrong October 4, 2005

chain fist bump 

when someone in the same room says or does something awesome and you want to give them a fist bump but are too lazy to go over to them, so you fist bump the other people around you until someone fist bumps the person intended to recieve the fist bump.

James: Remember when Steve burped the alphabet and did cartwheels at the same time?

Freddy: Yeah man, I gave him a chain fist bump for his excellence.
