look up any word, like donkey punch:
Neo-McCarthyism is when you investigate just about everything about everyone out of paranoia. Over-thorough secrurity inspections at airports are an example of Neo-McCarthyism. This term was coined by Mike Newhouse in the classic movie Dazed and Confused.
Mike: I didn't think drugs and alchohol were such a big deal they had to resort to Neo-McCarthyism to get rid of it.
Pink: I think they're just worried that some of us are having too good a time.
