When one masturbates while listening to loud club/house music

To play a bass guitar or bass instrument with such abandon you would be fired from a band if you played in it. Usually to let of emotion. Much like jerking offor masturbating without the mess.
1. I masturbassed and found a new song!

2. I masturbassed earlier to let of some steam.

3. The crowd loves it when I masturbass... too bad my band doesnt.
