Someone who often is alone. They usually have a few friends to no friends. Some people might take this as being stuck up but the loner just doesnt feel the need to reinforce the social feeling. But commonly there are places where a loner can feel more open becuase of the people around them or the setting (a particular classroom, or a person which they feel comfortable with, etc.) Most loners, if put in big groups by bosses, teachers, freinds, or even family, will often be quiet, has short answers, just stares off in nothing, or analyzes everyones reactions and bodylanguage.
They rarely have a boyfriend or girlfriend because they dont flirt, dont talk much, or give any social effort, as I said earlier. And that pretty much doesnt give the opposite sex any sign of interest consequently not getting asked out, and if they do get asked out they usually get asked out by someone who doesnt know them(loners are picky about who they let in their personal lives) and the guys they do like dont feel the need to flirt anymore becuase there was nothing coming from the loner.
