masterbanker 

A male who makes a living off selling his semen to a sperm bank.

Dude, that masterbanker makes $70,000 a year for wanking it and donating his junk.

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..'

masterbaiter 

On a fishing boat, one of the three common grades of baiters (those who handle their little fish in hope of attracting a bigger fish).

When I first started this job, I was just an Apprentice, but after long years of conscientious study and hard work, I made it to Journeyman. Now I'm studying hard and trying to work my way up to MasterBaiter!

A person how masted the art of bailing.
A masterbailer bails out of anything from internet convos to real needs while occasionally dropping some completely lame excuses.

Jude: Your bailed out of the chat last night, your such a masterbailer!
Nancy: Sorry man, I swear I fell asleep on the keyboard.

Jack: Why didnt Adam show up last night?
