YES. In my family there are tons. My mother's fault, really. Then I talk to my friends and they don't get me. Unfortunately, they're all Spanish terms.

Another thing we do a lot, is to quote movies' titles when we're having a normal conversation. Everytime we need to say a word which is the main word of a movie, we continue with the rest of the title, even if it has no sense in the conversation. The worst part is when we do it outside and people don't know the movie or don't make the conection, so they think we're talking rubbish.
