A sweet loving ugly boy with a peng smile and always knows how to make a person who is in a bad mood turn happy also he is a friendly, caring, loving person. On the other hand he can be annoying but knows his limits and never lets anyone down and he is cheeky one. Junior is a guy who knows how to bang convo with a girl and when he’s inna relationship he will make sure a girl is always happy around him and compliment his own girls looks. One thing about Junior is that he is not afraid of being rejected by a girl he will simply move on with his life. Finally, when u don’t see him for a long time it means he is plotting lots of things that will make him succeed in life and will curve people if he has to.

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.

junior: HAHAHHAHHAAHAHAHAHAsucks.
