Outcast

Someone who doesn't label themself to any specific identity. They are often overlooked by the rest of the world and usually don't 'fit in' with the rest of the scene. They are also commonly used by what friends they think they have, as the outcast being a nice person and all. Outcasts have a harder time fitting in or finding friends as their interests are probably not what's mainstream and popular. Afterall, if everyone was all interested in the same thing (which most are) the world would be a boring place. A good example would be someone who is a roller coaster enthusiast in school, where no one else gives 2 hoots about that subject matter. It is common that an outcast only hangs out by their friends if the friends have nothing else to do...and use the outcast as a last resort.
