The kid who never talks in class, and when he does shit is probably about to go down.

The type of kid who's usually introverted and never really talks. They are usually really smart and probably capable of killing your entire family.

Everybody cool til' he pull out an Ak47 to yo fuckin face

The quiet kid, often the student in class that goes unnoticed. There are voluntary quiet kids, and there are involuntary quiet kids. Voluntary quiet kids are often loners, who are very self-sufficient, and can in some cases be motivated to stay unnoticed, or low-key. Involuntary quiet kids may have shy tendencies, and may actually be too timid to initiate friendship. Often labled as mysterious, or weird by classmates. Many have suffered negative lables by judgemental people such as: gay, emo, goth, 'mental', shy, rude, mean, stuck-up, and boring, which is unfair to the quiet kid, because most people (yes, even teachers), make these judgements without taking the time to understand or get to know the individual. Often the quiet-kid is not "boring" as some may suggest, but instead may not feel that the people in their environment are good for their personality, especailly with most people being so judgemental anyway.

A kid who is very smart wants to work or sit alone and makes very little noise (Usually introverted or ambiverted). And other kids always think they are sad or depressed.

The kid in the back of the classroom who is rarely ever spoken too. This kid could be the smartest kid in the class, but every time he says anything, he isn't listened to, and others around him steal his answers and yell them out. This is the kid who is not well known by most of the class. When students pass out papers, they say "who is (insert name of the quiet kid here)?" The only time people ever talk to the quiet kid are when they need something. It's never to talk about TV or video games or the internet, it's always "what did you get for number 3?" or "what was the homework for English class?" The quiet kid will go home every day, with a huge backpack, on the bus, and one day he'll stop showing up at school, and no one will notice or care. People will assume he switched classes and went somewhere else. It would be as if he never even existed...

They are pretty chill and usually pretty smart as well. They rarely ever talk and are pretty good friends. If you piss them off, you won't survive the school year.
