A+ 

The highest school grade ever. There are 2 reasons people hate people with A+'s:

1. They're kinda jealous.
2. The people who get them are despised because instead of partying and drinking beer until they couldn't see straight lines or breathe anymore, they spent nights studying for that final exam so they won't get SWORDED! by their parents.

I got an A+, then when some punk saw me with that, he tried to shoot me, but only shot cars behind me causing their alarms to go off.
