Underclassmen

[Justin Bieber]

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 cant 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.

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...
