a demonic group of high-schoolers that is at just the right time in they're career so that they're just old enough to be considered upperclassmen, but just young enough to not have the stress of college apps like the seniors. this results in a tremendous and annoying ego enhancement, making them the most troublesome and/or obnoxious class in the school.
freshman: (to junior) do you know where room 231 is?
juniors: yea its down the hall to the right (freshman leaves and junior and friends laugh because they know it's actually on the other side of the school)
junior: (to senior) how are the college apps going?
senior: not too well, i haven't finished yet AND i got deferred from my first pick.
