upperclassmen

10th,11th,and 12th graders in high school who think they have the right to be complete assholes and be jerks to all of the freshman just because they have been there longer.

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

upperclassmen

The older people in high school(usually 11th and 12th graders) that think they have the right to leave out freshmen, treat them like they don't matter and always telling them to fuck off. They also tend to get lazy as fuck and party their dicks and pussies all night long on Fridays and weekends.

Guy 1: Hey dude can you please take me out to that party that's going on this Friday?
Guy 2: Dude, what grade are ya in?
Guy 1: Freshman...
Guy 2: HAHAHAHA!!! I'm part of the upperclassmen!!! Fuck outta here dude!!! Go home!!!

Underclassed

When you feel like everyone else around you is of a higher class

I feel so ‘underclassed’
