On a cruise ship in 2026, the word "banana" is most commonly used as a crew-specific slang term for a passenger who is perceived as being difficult, demanding, or a "complainer." It is not an official emergency code like "Bravo" (for fire) or "Alpha" (for a medical emergency). Instead, it is a discreet way for crew members to alert one another that they are dealing with a person who might require extra patience or who is likely to leave a negative review. Some crew members use it to describe a passenger who "slips up" or makes a scene, referencing the classic banana-peel joke. In certain maritime circles, it can also be a lighthearted reference to a "Banana Boat" excursion. However, if you hear a crew member whispering the word to a colleague while looking at a guest, it’s a safe bet they are using the slang for a high-maintenance traveler.
