Tacaño

Tacaño is a Spanish word that means "cheap" or "stingy". The great thing about this word is that you get to use a special hand gesture along with it (as shown in the picture here). You basically make a fist, and then hit your elbow with your other hand. I think it's supposed to mean that your fist is holding money, and you're trying knock out the money with the other hand. Be careful, however, as this is very similar to an obscene gesture called the bras d'honneur, where the only difference is that your bottom hand goes on the inner part of your elbow. If you call someone a "tacaño" and then use this incorrect gesture, I can promise you there's gonna be trouble.
