Blumpoff 

A competition held between 2 or more couples to see who gives and receives the best blumpkin. Points are won for large shits and more intense ejaculations.

Good luck at tonight's Blumpoff, I hear Jessica is a seasoned pro.

backdoor blumpff 

A qweef from the anus caused by too much anal sex; therefore creating a loose asshole where air can not be contained. So during anal sex, after, or just random blumpffs that are unable to be contained.

I had no idea too much anal would cause me to have so many backdoor blumpffs.
