The two highest grades in High School before College. They are Juniors and Seniors, and are absolute dickheads to lowerclassmen just because they exist. However, not all are this way, but most of them that you'll meet will hate lowerclassmen for no reason. Once lowerclassmen become upperclassmen, they want that feeling of power, and will repeat the harassment that the previous upperclassmen did to them.
Upperclassmen: Haha! You lowerclassmen are nothing but mislead fucktards that don't know your place! We will pick on you, treat you as inferiors, and make fun of you until we leave out of this fucking dump for good! Pick up my shit, hand it to me, and don't make us mad!

Get the Upperclassmen mug.by KattTheWeeb August 1, 2018
Get the Upperclassman mug.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.
Freshman: Uh ... yeah?
Upperclassman: Go clean the floor with your tongue.

Get the upperclassmen mug.people who are "upperclassmen" aren't immature 9th graders. they are seniors and juniors, or the top grades in a school. everyone other than the youngest. freshman in high school are not upperclassmen, and shouldn't call themselves upperclassmen. 6th graders are basically the same social status as 9th graders, if not better.
