Tammy and I have been on many cruises where we noticed an upside-down pineapple on someone’s cabin door and wondered what it meant. The symbol has been circulating for years, and many people believe it’s a secret code for swingers or couples looking for a little extra fun on their vacation.

But is there any truth to this unofficial symbol having a secret meaning?

According to various sources, an upside-down pineapple on a cruise ship door can indicate that the cabin’s occupants are open to meeting other couples for “adult fun.”

However, it’s important to note that not everyone who uses this symbol is necessarily a swinger. Some people enjoy the attention it brings or use it as a conversation starter.

Regardless of its true meaning, the upside-down pineapple has become a popular topic of discussion among cruise ship passengers and has even sparked some controversy in recent years.

The Upside-Down Pineapple Symbol

If you’ve ever been on a cruise, you may have noticed a peculiar symbol: an upside-down pineapple. These cute pineapples are not just a random decoration but rather a secret code swingers use to signal their availability for a partner swap or other sexual activities.

The history of the upside-down pineapple symbol is rooted in the fruit’s association with hospitality. In the past, pineapples were a rare and expensive delicacy, often reserved for royalty, and were considered a symbol of hospitality.

When pineapples became more widely available, they were used as a symbol of welcome and hospitality. The tradition of placing an upside-down pineapple on one’s doorstep or in a business establishment became popular in the 18th century.

Today, the upside-down pineapple symbol has taken on a new meaning in the world of swinging. Couples open to partner swapping or other sexual activities often display the symbol on their cabin door or other personal items, such as phone cases or tote bags.

Let’s not forget pineapple tattoos, pineapple emoji, and even a pineapple badge. This allows other swingers to identify and approach them discreetly.

It’s important not to judge, as many of these are committed couples in a committed relationship.

Not all cruise ship passengers who display the upside-down pineapple symbol are swingers searching for a swinger party, so remember it is not always a symbol for swingers.

The SECRET Code You Don’t Know about | Cruise Ship Swingers

Some may be unaware of its meaning or use it as a trendy decoration without understanding its significance. It’s also worth mentioning that swinging is not for everyone and should only be practiced by consenting adults.

In conclusion, the upside-down pineapple symbol is a secret code used by swingers to signal their availability for partner swapping or other sexual activities.

Its history is rooted in the fruit’s association with hospitality, but its meaning has evolved over time. If you come across the upside-down pineapple symbol on a cruise ship, it’s up to you to decide whether or not to approach the person displaying it.

Cruise Ship Culture

Door Decorations

One of the most interesting aspects of cruise ship culture is how passengers decorate their cabin doors. This is a way of expressing their personality and interests, and it can also be a way of identifying themselves to others on the ship.

Some passengers use magnets or stickers to decorate their doors, while others go all out with elaborate displays that include lights, pictures, and even small toys or souvenirs.

Swingers will often use a magnetic pineapple sticker or several different types of decorations to meet like-minded people.

Social Interactions

Cruise ships are also known for their social atmosphere, with passengers often striking up conversations with each other and forming new friendships. This is facilitated by the many activities and events that take place on board, from pool parties and game nights to dance classes and trivia contests. Social media has also become a popular way for passengers to connect with each other before and after the cruise.

In addition to socializing with other passengers, many cruisers also enjoy interacting with the crew. This can include getting to know their cabin steward or waiter, attending crew talent shows, or participating in behind-the-scenes tours of the ship.

The crew members are often from all over the world, so this can be a great way to learn about different cultures and make new friends.

Overall, cruise ship culture is a unique and fascinating phenomenon that offers a wide range of experiences for passengers. Whether you are interested in door decorations, cabin door symbols, social interactions, or all of the above, there is something for everyone on a cruise ship.

Adult Fun and Swinging

Adult fun refers to sexual activity between consenting adults. Swingers engage in partner swapping, also known as wife swapping. This involves couples exchanging sexual partners with each other. It’s important to note that swinging is a consensual activity and requires the agreement of all parties involved.


In conclusion, the pineapple on a cruise ship cabin door is a secret symbol of the swinging lifestyle. It indicates that the people in that cabin are open to meeting other couples for adult fun. Swinging is a consensual and non-monogamous activity that involves couples exchanging sexual partners. If you’re not interested in swinging, it’s best to avoid cabins with pineapples on the door.

Misinterpretations and Jokes

Upside-down pineapples on cruise ship doors have been a topic of many jokes and misinterpretations. While the symbol is often used as a code for swinging or “wife-swapping,” there are instances where it has been used for other purposes.

Tiktok User Experience

Recently, a Tiktok user shared a video of her mother and her husband decorating their cruise ship door with an upside-down pineapple. The user’s mother did not know the symbol’s meaning and thought it was just a fun decoration. The video went viral, and many viewers found it amusing that the mother had unknowingly used a symbol associated with swinging.

Blogionista Travels Story

In another instance, a blogger, Blogionista Travels, shared a story about how she and her husband mistakenly used the symbol. They had seen other passengers with upside-down pineapples on their doors and assumed it was a trend or a way to show off their love for pineapples. However, they soon realized their mistake when they received an unexpected invitation from another couple to join them for a “private party.”

While these stories may seem humorous, it’s important to remember that the upside-down pineapple symbol is a serious code used by swingers to find each other on cruise ships. It’s essential to be aware of the symbol’s meaning before using it as a decoration.

In conclusion, it’s crucial to understand the significance of symbols before using them as decorations. The upside-down pineapple may seem like a harmless decoration, but it has a deeper meaning that should not be taken lightly.
