underclassmen

usually meaning the lowest grade of students in a school.(9th,10th,11th grade is also debatable, for examples)
in movies and t.v. shows, they are usually depicted as beady eyed kids that for some reason envy the upperclassmen almost as if they are god amoungst men..
but in real life they are generally ungreatful little snots that think they are tough/cool.oh and i never said they are all like this...

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.

Underclassmen

Children who are obsessed with making pointless Facebook statuses, usually consisting of "LIKE DIS STATIS IF U WANNA B IN MY BOX!!!" or "Omgg he dusnt liek me....**** lol (:" and potentially causing social problems/embarrassing themselves (you can't spell embarrass without ASS!) by copy/pasting pictures of themselves next to some other child in Microsoft Paint and attaching a stupid caption written in Comic Sans asking people to pick who is more attractive, then tagging random people in said picture on Facebook. Belong on MySpace with the other children.

upperclassmen

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.

"wow 7th grader you can't be mean to me. you're talking to an upperclassmen"-freshman
"actually you arent cool and your a freshman, not an upperlcassmen. you aren't a senior or junior, yeah your not coool."-7th grader and the rest of the world

Underpass King

Anyone who plays CSGO like an absolute nig piece and hides out in underpass on the mirage map all game. Underpass Kings tend to have the aim and reaction time of a potato. But despite all this, Underpass Kings do have their moments.

The Underpass King waited out all game at the underpass despite his teammates' calls for help

He sprayed his gun like an Underpass King as the bullets made a full circle around the opponent's head.
