A student (usually high school junior) who racks up multiple extracurricular activities with the sole purpose of stuffing her/his college application. Has no passion for any of these activities whatsoever, and attempts to get her/his fingers into as many pies as possible (however shallow).
Also attempts to cozy up to successful students (mostly Ivy-bound seniors) and learn the secrets of getting into college.
Examples of extracurriculars include: community service, Model United Nations, debate, French club, etc.
Wow, Chloe B. just jumped into every single club photo so she could say she was in all those clubs! What an extracurricular whore.
