Remember back in high school, when there were different "groups"? You may have called them cliques or crowds. Some were preps, some were jocks (many were both). To my memory, hipsters were not a thing then, but goths were. I think emo, too? And at a magnet school I always felt that nerds got a lot more respect than Hollywood ever depicted. There were studious Asians and lots of gangbanging Asians, too. That was K-12 life. In adult life, we still have crowds, and I see a ton of confusion on an almost daily basis that surrounds the usage of which group someone belongs to. But set aside the groups themselves, even the nomenclature gives us trouble.
