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.
