look up any word, like lesbiauntie:
 
1.
Defined as a person in high school who will take every AP class available for the sole purpose of leveling up their class rank or GPA, and not for the education. Makes up roughly 15% of our class of 2007.

Classes may include, but are not limited to:

AP Chemistry, AP Statistics, AP Biology, Honors Anatomy, AP Enviromental Science, AP Psychology, AP Sociology, AP Human Geography, AP European History, etc.

Everyone in the top 25% of our class has taken, or are taking, more than half of these classes..AT THE SAME TIME!
"Yo dude what classes are you taking?"

"Oh...AP Comp Sci, AP Enviro Sci, AP Bio, AP Stat, and some other crap"

"THE HELL?!"

"Dude I need to bring up my rank. I'M ONLY 23 (out of 180)! I NEED TO RANK IT UP"

"...what a rank whore"
