masterfaker 

a person who has fooled everyone into thinking they are someone they aren't. Usually with lies and manipulations.

One who has convinced all others they are a saint but you know the truth.

My boyfriend is a masterfaker, he acts all proper around me but when he's not with me, he's drunk and hanging all over other women.

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..'
