Used to describe the phenomenon of achieving 13 wanks in a day.

Common with self-employed geeks and students.

Comparible to the finite number of times you can fold a piece of paper, the wanker's dozen is rarely beaten.

Derived from bakers dozen, except the bread rolls are spooge-filled tissues
Typical conversation:

M: "My bell end is red-raw."

J: "Why's that?"

M: "Wanker's Dozen"

J: "I am Not suprised"
