Two or more people who share everything with one another, knowing they can be trusted. People who would, if needed, take a bullet for their friend. Two or more people who, through all the new friends, new hobbies, new jobs, rough times, and high school, are ALWAYS there for each other, no matter how busy they are. A best friend is someone who can make you feel better no matter what.

Someone who you can be completely comfortable and crazy around. Someone who doesn't care if they cause physical pain to you when you do something stupid - "you deserved it." Someone who will come pick you up in the middle of the night when your boyfriend's being an asshole. and they're twenty miles away. Someone who can be a complete bitch to you one day, then totally nice to you the next and expect you to forgive them - and you DO forgive them without hesitation. Someone who you fight with and yell at and hate constantly 99% of the time, and then get along five minutes after you just fought. Someone who, when you lose them in a big amusement park, you begin crying because you feel so lost without them. Someone who's not afraid to call you fat and ugly on your bad days, and then fat and ugly or your good days too. They're kind of like tumors in your body that never go away.
Teacher: "You two girls have been arguing all the way down the hall!"
Girl: She's being a bitch and calling me names and hitting me! She's really making me angry!"
Teacher: "Then go to the office and explain to the principal what she's doing and saying."
Girl: "Oh no! I could never do that! She's my best friend!"

Trent lost, so he changed it to best of three. He lost again, so he changed it to best to three to string out his loss.

A short, troll-grammar way to say "best in the world," used mostly in Blizzard's World of Warcraft. Sometimes the player's class is inserted in between "best" and "world"
