When you put a fist in someone's ass and open your hand as wide as possible. This is also known as a "Staten Island tsunami"

I was fisting my girlfriends ass and decided to go for the flumper.

Flumper 

This word is a portmanteau of 'flabby' and 'dumper'. A flumper generally occurs when an obese person loses most of the excess weight, but the posterior retains its obesity, resulting in an average or even slim individual with a backside that sags grotesquely.

"She was damn hot when she was walking toward us, but after she passed by, I looked over my shoulder and saw she had a terrible flumper."
