Message to people on the internet

So you've just learned the term "opportunity cost", have you? That's great. I've seen many, many people using that term around the internet lately. One of them used it in a way that made me think "yes, that makes their point clearer" and not "someone has a dictionary and isn't sharing".

Remember, just because you can use a fancy term doesn't mean you should. I'm firmly of the opinion that when you sacrifice clarity for making yourself look clever, your writing has lost something.

There's a term for that, I'm sure.
