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!"

Farturbating 

Farturbating, the less-acceptable version of the farting and masturbating incarnations (the other being Masturfaring), is when one elects to masturbate after they have already begun to pass gass (i.e. fart).

The order of these activities is crucial : If you are gassy (i.e. farting) and you elect to masturbate, you are Farturbating. Congratulations. If you begin masturbating and realize you are gassy, though continue, you are masturfarting. Also, congratulations.

For disambiguation, see FARTURBATING, and the sister activity, QUEEFURBATING

I was gassy, but didn't want that to prevent me from re-living my makeout sesh with Britney last night. I had to start farturbating
