masturbass 

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.

Masturbaker's dozen 

The pinnacle of all dedicated feckless cum-shedders whereby the participant aims to ejaculate more than 13 times in a 24 hour period. 13 loads in generally accepted by industry insiders as being the level that separates the men from the boys.

'I did it , I did the masturbaker's dozen! Admittedly the last six were with a floppy and the jizz was purely gaseous, but by golly I finally did it. Now it's off to the doctor for me to get some ointment for the blisters and tennis elbow..'
