A “classhole” (class + asshole) is an annoying person at school. “The jerk of the class!” was a definition in the Urban Dictionary on February 17, 2003. A popular definition was cited on Twitter on August 29, 2012:
 
“Classhole (n) : That one student who decides to be present in the class even after whole class unanimously decided for a mass bunk.”
 
“BajaRat failed all classes except one, otherwise he’d be a total classhole” was posted to the newsgroup misc.immigration.usa on August 4, 1998.
 
The term “classhole” can also have nothing to do with school. The Online Slang Dictionary definied the term on January 27, 2014:
 
“A high class and cocky or egocentric and bombastic asshole who thinks they are better than everyone else.”

At BU, they’re called classholes. At many other schools, gunners. Still others have no title but are reserved a snide look and a withheld invitation to any social invitation outside of the law school.

I don’t know when or how it started, but these brown-nosing, overachieving, socially inept book worms have an undeserved bad reputation in law school.
