Misused

Here's two words that I frequently hear used incorrectly and it drives me insane:

1. Factoid: This word is often used to refer to a clever piece of trivia, but just because that use is common doesn't mean it's right. This word did not even exist until '73, and it has a very specific meaning. In the same way that a humanoid is something that seems human, and a planetoid is something that looks like a planet, a factoid is something that seems like a fact, but is it. I believe the term was originally used in reference to Marilyn Monroe being an orphan. The belief was so widely held, it was thought to be true... but it wasn't
2. Unique: Uniqueness is like pregnancy in that it's a binary situation. You can't be "sort of" pregnant. A comedian can't be "kind of" unique. For some reason, I see this misused most in interviews with people in entertainment (TV, movies, etc.)
