v.it., The act of male masturbation whilst seated on a toilet. This term originates from a play on words; one's hand is on one's "cock", thereby conducting the act of masturbation. As this occurs, one is also seated upon a "John", or toilet. Often the physical stimuli of the act itself is inhanced by pressure on the prostate from passing feces.
