Cruise ships offer a unique blend of adventure, relaxation, and also some unexpected social interactions. One intriguing aspect that has caught the attention of many cruisers in recent years is the upside-down pineapple on the cruise ship doors. But what does this symbol mean?

I’ll explain it to you and tell you how this “custom” has evolved in 2024.

The Secret Language of Pineapples at Sea

For some naive people, a pineapple might seem like a simple tropical decoration, but it actually carries a hidden meaning in the cruising world. The upside-down pineapple is a discreet symbol used by some cruisers to indicate their participation in the swinger lifestyle, a community that embraces partner swapping and open sexual exploration.

This symbol has its roots in the broader historical context of pineapples as a sign of hospitality and luxury. However, it takes on a more specific connotation on cruise ships, helping like-minded individuals identify each other without drawing unnecessary attention.

Although, now that the meaning of this symbol has spread to other passengers, the value of its use has been somewhat lost. In fact, I must admit that it is being used less and less, specifically because it is no longer a secret signal.

The Pineapple Code: where should you put it?

This symbol has become so famous, especially because it is so easy to use. It might appear as a magnet on a cabin door, a sticker, or, more rarely, even as a playful accessory on one’s person, like a pineapple-themed piece of clothing. This allowed swingers to signal their interest in encountering others who share their lifestyle in a subtle yet practical way.

Misconceptions and Respectful Conduct

A thing that I really want to underline is that not everyone displaying a pineapple may be up for it. Many cruisers are completely unaware of its connotations and remember that people use it purely as a fun decoration. Moreover, it’s always important to remember to approach others with respect and discretion, as the swinging community really values privacy and consent.

Is it a growing trend in 2024?

The phenomenon of swinging on cruise ships is reflective of a broader trend, where people seek out unique experiences and connections while on vacation. As I said before, however, it seems that this symbol is falling into disuse. However, I’ve noticed that I’m seeing more and more ads for swinger-specific cruises organized by specialized agencies. For example, the ones organized by, an agency that offers optional clothing cruises with erotic entertainment, sexy theme nights, and DJs.
