The act of self pleasure while listening to dubstep or any other bass heavy music.

Toby: Did you see Danny at that Excision concert last night?
Luke: Yeah man, he was totally masterbassing all over the place.
Toby: And when that bass dropped?

Masterbathing 

When you're taking a bath, jacking off and then bathing in your own semen.

"Goddamn it David, your masterbathing clogged the drain again!"

"Yeah, Kirk seems like a smart guy, but he's just too busy masterbathing to actually teach us."

Masterbathing is more private and intimate than dunk-tank-wanking.

Tad was masterbathing for over an hour today, and now there's no hot water left!
