Phoop

v. Simply pieced together, the onomatopoeic word phap (also spelled fap, that is used to describe the sound made during masturbation) is spliced with the word poop, meaning simply: To masturbate while defecating.

Brian: Oh man bro, I phoop so often that my bathroom consistently smells of dump and cum.

Jacob: What the fuck man, thats nasty.
