New and Improved! Crew slang! Are they talking behind our backs?

Code Oscar means man overboard. So if you hear them say that over the speaker, you know somebody went overboard.

Code bravo means that there's a fire on board. So, when you hear that, they'll probably say what area it is.

Washy washi means sanitize your hands or wash your hands.

Tranquilo or tranquil means chill out or relax and that's what they do when they have their time off.
