look up any word, like donkey punch:
 
1.
It is when you choose the 6 hardest subject at school: Physics, Biology, Chemistry, English, Maths B and Maths C. Called suicide six as it's so hard it makes you want to suicide.
Karmen: What subjects do you do?
Leanne: Oh I do the suicide six
Karmen: WOAH SH*T TOO GOOD!
