Process of
masturbating while
taking a shower. Very convenient, due to the fact that most often ejaculation can easily be washed down the drain, the running water makes the activity more pleasurable, and
practically every substance around is a lubricant.
Roommate: God, why does it
take so long for Jacob to shower?
Passer-by: Isn't it obvious, he
probably does showerbation every chance he gets!
Roommate: Oh gross, I hope he washes all the jizz
down the drain.
