Demisocial

Someone who is not exactly antisocial or introverted, just very particular about the people they hang out with or the places they go or the things they do. Inspired by the word "demisexual".

"Hey... are you going to Bob Sacamano's New Year's party?"

"Nah... I'm not really into big crowds. Don't get me wrong...I'm not a loner. I'm just Demisocial. I just don't have a good time at parties that big. 5 or 6 people playing poker is more my speed."
