A trendy new dance generally reserved for those with the the rhythm of a usher, chris brown, or MJ, but that should be attempted by all. The dance goes as follows:
1. The beat kicks in to a song
2. Jump while simultaneously fist pumping and throwing your knees in the air
3. Hop backwards while jumping
4. Smile, laugh, and sign autographs....you are now the life of the party
5. Post video on you tube and reference @bwarner and @30PercentHero

Recommended song: "one" by swedish house mafia

Clap, clap, thump, thump, thump

A Fist Pump Fudge Factory is a sex technique where a Man is "pumping" his penis until ejaculation into a woman's mouth while another woman is waiting for the man to stool on her vagina. Once the feces is on the woman's vagina she then proceeds to use the feces as lubrication for the other woman's fist to enter her vagina while the man drinks both of the women's breast milk.

When one uses ones bare fist in a pumping motion to unclog a plugged toilet.
