A classhole is a rare breed of student, the kind who insists upon commenting upon absolutely
everything the professor says, even if his/her comment is as meaningless as nodding and verbally giving his assent/dissent. The classhole also answers just about every question asked, even when everyone else is sick to death of hearing him/her spew their
insignificant opinions about topics nobody really cares about in the first place. Class is a time to
shut your mouth and listen to the professor, who has years of education and probably four or five different diplomas to boot; the knowledge of the classhole pales in comparison, but this is a fact that is only evident to everyone else in the class. The classhole, so smitten with themselves, remains ignorant.
