Masturbaywatch 

To watch the American lifeguard-inspired drama 'Baywatch' for the sole aim of masturbation

'So I was having a masturbaywatch to Pamela Anderson last night when, on the vinegar strokes, the camera panned to David Hasselhoff. As I understand, this now means that I must be a raging homosexual. Do you know where I can catch a matinee of 'Mamma Mia' and follow it up with some good old-fashioned sodomy so as to assimilate effectively with my newfound kin?'

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..'

masturboxing 

A man who beatboxes while masturbating.

I was sitting in the bus the other day when I heard a guy behind me beatbox, so I turned around and saw that he also was masturbating. I was like... "WTF, MASTURBOXING?"
