uberclassman

A highschool upperclassman drowning in a mixture of pride, overachievement and entitlement. Amazed by their own intellect and personal growth, they often go on "crusades" to right social wrongs(crusade being defined as :a.) a minor inconvience b.) a large number of people dying on the other side of the world(uberclassmen think its revolutionary to say that genocide is bad)).

Wow, that uberclassman is a prick.

Upperclassman

Someone who is older than you, or higher than you. Translated it means senpai in japanese.

"He greatly respects Mamoru, who is an upperclassman at his school."

upperclassman

Any student in a high school other than a freshman. These students are usually pretty normal, but for some of them, the evolution from frosh to non-frosh makes them into total jackasses. These jackass-upperclassmen should be avoided by freshmen at all costs.

Upperclassman: Hey, you're a freshman, right?
Freshman: Uh ... yeah?
Upperclassman: Go clean the floor with your tongue.
