A person who threatens people with a brain that is smart as a dude taking a dick pick and giving it to an underaged child

To be aggressive or rude to another person.

Bullies are scum, pure and simple. They torment people who can't defend themselves, they revel in the suffering of innocent people who have never done anything to hurt them. They are the REAL reason for the Columbine shootings, they are the main reason for kids dropping out of school, or worse, commiting suicide. It's not just kids who can be bullies, teachers can be even worse, seing as how they have authority over the kids. But when their victims stand up for themselves, their true nature shows: a cowardly, spineless worm.

A young hoodlum who revels in making peoples lives a misery during school years. Happily though, when they grow up they will have nothing more to look forward to than getting anally penetrated every day by fellow prisoners in the shower, or, by the prison wardens truncheon ;D

A person who makes fun of others based on their own insecurities about life.

one that attacks or speaks ill of someone else.

Someone who is completely insecure about their own physical appearance or mental abilities. A bully can be a friend of many years, someone you don't even know though they are often spurred by jealousy they will isolate, ignore, tease, make fun of and ultimately mentally or physically abuse you. Can often be so subtle that other people don't even notice so you once again come out in the bad light. Bullies usually are not to be worried about but can often put a huge amount of stress and anxiety on a person. More so hurtful if they are a close friend. Don't worry though, bullies often end up lonely and without friends, you are strong ignore them :)
