Top definition
Someone who enjoys tormenting others with maths tests, puzzles or trivia.

Often found in maths classes across the spectrum of education -behind and in front of the teacher's desk. The Sado-mathocist can be identified by their half chewed down pencil from an over-indulgent sudoku addiction, graphical calculator with worn down equals button and a generally quiet demeanour, their mind too busy with the possibilities of oncoming numerical torture.
I was about to make it through my morning physics class, until my hangover was interrupted by a sado-mathocist ambushing me with a mechanics question.
