The act of masturbating while taking a shower. The wetness and steaminess makes it feel amazing, yet it usually takes a little longer to have an orgasm. It is also very efficient in terms of cleaning yourself off afterwards.

Daniel: "Nice, dude, that must have felt awesome! Shasturbation is the best!"
