I posted something like this on my own blog before, and I feel it's good mugalomaniac material. So I tried to recreate it (more-or-less) from memory.
Telltale signs of an outright Math mugger:
1) You refer to something you don't know at lambda or mil.
e.g. He's talking lamba to me, or, Teacher, the note are mil to me.
2) You use vectors to plan your journey in the shortest time. Then find you can only move in the Y-axis by taking the stairs or jumping off 3 storeys (3j)
3) You formulate AP to calculate how many scoops it will take to finish each grain of your chicken rice assuming you take 40 grains per spoonful.
4) You feel naked unless you bring your GC out with you.
5) You write your GP essay in Mathlish.
e.g. 3 dots= therefore, upside down 3 dots = because, slashed equal = not equal.
6) When you are asked to differentiate between 2 objects, you put one on top of the other.
7) You spell function room as f (room)
8) When you are asked to cut a cake you attempt partial fractions on it.
9) Your idea of a Gameboy is plotting graphs on your GC in polar mode. (Look for it, it says "pol")
10)You write squiggly lines below each i, j, or, k you write in a sentence. You sometimes use a thicker pen to bold them for variety.
