1.) Kiefer- a guy who usually acts like he doesn't care but really does. afraid of being hurt, he puts up walls that are hard to climb, but once you make it over it's totally worth it.
2.) a Kiefer always has your back, and knows how to make you feel better when no one else can. he is opionated and will stand up for what he believes in. he doesn't care what other people think and he says what is on his mind. he doesn't like other people very much, especially not immature ones. he likes to be alone, but when you do hang out with him, its some of the best times ever. he never says anything nice (or sorry) unless he really means it. girls secretly have crushes on him, but he seems unnatainable, so they don't go for him. all the girls want to kiss him.

3.) "to pull a Kiefer"- to act like you don't care about anyone or anything, but in reality, you care more than most people do.
4.) Kiefer- a superhero of American background with amazing musical and athletic abilities.

A guy who's basically the best a girl can get. He's super sweet and kind of adorable. Most likely a good soccer player, he's got a pretty fab body too.

He's the kind of guy who when you first meet him you think he's perfect, but then you realize, he actually is.
Girl 1: Have you seen Kiefer today?
Girl 2: Yep, i still can't believe i'm dating him :)

A total hot guy that you will fall for. Bad news is he is the most confusing creature on the planet who is bi-polar as Antarctica. He will make you feel stupid in front of his friends as pay back for not buying him a hot dog at a football game. Waste of time.
