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..'

masterbask 

When no one will give you the gratification of a job well done, you are forced to masterbask in your own accomplishment.

No one would give me the credit I deserved for a great project at work, so I was forced to shut the door to my office and masterbask.

I had just finished painting the bathroom and showed my wife, she said "fine" but you have more work to do. I needed to masterbask in my accomplishment. Then I felt better.
