Sudoku-Slap 

If you got a wet newspaper, so the ink is running, you take out the sudoku page and slap someone in the face with it so that it leaves a mirrored print of the sudoku.

Robert was acting like a twat and bugging me with Jeroen's laserpen all the time, so he left me no choice but to sudoku-slap him.

commit sudoku 

A deliberate misspelling of "seppuku" — the samurai ritual of suicide by disembowelment. The misspelling removes the direct reference to suicide, replacing it with the name of a popular and frustrating number puzzle.

I have brought great shame to my brethren. I must now commit sudoku.

Para-Sudoku-Psychosis

An abnormal, trance like state of mind generally attained after prolonged periods of staring at a Suduko that has reached a point
where you are completely unable to prove another number if your life depended on it.

Bob: Hi Sally, I was just wondering if everything was ok? I saw you from accross the cafe and, well to be honest you've been sitting there for
over and hour and you haven't moved a muscle.

Sally: Huh? Bob! oh Bob! Thanks Bob, I must have had a bad case of Para-Sudoku-Psychosis. I get like that sometimes when I get stuck
on a difficult Sudoku.
