An over exaggerated term for shampoo or soap when it gets inside your pee hole while attempting to masturbate with it.. Resulting and ending in either one or several "stop-start" pissing sessions while the person is screaming about the flaming sensations that have been inflicted "down there"
Jack was out of lube, so shampoo sounded fine.. Mr. pee hole said otherwise, as poor Jack shed his tears as he slowly and painfully pissed out the Lava Lube that he mistakenly used that night. Therefore, turning his pleasure session into a pain session.....
