Fistumba 

A fistumba is any injury or mark sustained during the processes of high-fiving, fist-bumping, chest-bumping, etc. Usually bruises, red knuckles, sore hands, etc. From the goofy injuries people get while doing Zumba exercise. This word first aired on the show "A Way With Words" in late 2012 and was called in by a school teacher whose students were using it.

"During band practice, my saxophone solo was harder than usual because of the fistumba on my right hand."

fisturbating 

To masturbate by inserting one's fist into one's own orifice or orifices. Artificial or disembodied fists may also be used. The word is a hybrid of "Fisting", "Masturbating" and "Sophisticated", and as such could be considered a sophisticated form of self-fisting.

"I wouldn't go in there Gavin, Tylah is Fisturbating."

Bryce: "Dan, if you don't sort that shit out my fist will be up your ass"
Dan: "I can fisturbate MYSELF!"

Fistubate 

Shoving thy fist into thy no'no regions hard and fast.

When I fistubate with myself, I always walk away sore yet complete.

I caught Sally fistubating earlier, and now here knuckles smell repulsive.

Why do Republicans fistubate to each other all of the time. It must get very cyclical watching each other ram fists up their dirty ass's and vagina's all day.
