A Former Cruise Ship Worker Uncovers the Surprising Adult Meaning Behind Wearing a Black Ring
If you have ever spotted someone on a cruise ship wearing a simple black ring on their right hand and thought nothing of it, you may have unknowingly walked past a secret signal hiding in plain sight. Crew members who spend years aboard large ocean liners tend to pick up on the behind-the-scenes culture of these floating resorts, including the subtle ways certain communities identify one another in shared public spaces. Lucy Southerton, a 28-year-old former cruise ship worker from Birmingham, England, who clocked up a decade at sea, recently shed light on this very phenomenon. She shares her experiences from life aboard ships on her YouTube channel “Cruising As Crew,” covering everything from workplace dynamics to the more colorful aspects of passenger culture.
According to Lucy, the swinging community has developed a number of discreet visual codes to help members recognize each other without broadcasting their lifestyle to everyone around them. The most well-known of these is the upside-down pineapple, which has become widely recognized even outside the community, appearing on cabin doors, clothing, and jewelry. Because of that mainstream awareness, however, the pineapple has arguably lost some of its effectiveness as a subtle identifier. That is where lesser-known signals come in, and the black ring is one of them. “One other that I’ve heard is there’s a black ring on your right hand,” Lucy explained in a 2023 video that has since racked up more than one million views.
The black ring worn on the right hand is considered one of the more understated signals within the swinging community precisely because it is so easy to dismiss. Lucy herself acknowledged the awkward potential of misreading it, noting “you can never really be sure if that’s just something they like to wear, or whether it is a signal.” Unlike the pineapple, which tends to be placed in very intentional locations, a black ring is a common enough piece of jewelry that it gives its wearer complete plausible deniability. This subtlety is part of the appeal, especially for couples who are interested in the lifestyle but prefer to keep that part of their lives private. The signal was not created by cruise companies or any official organization but was instead developed organically within the community itself as a way to find like-minded people discreetly.

Lucy also dug into the broader vocabulary used within the swinging world, explaining the various terms members use to describe themselves and their preferences. “There is a unicorn, which is basically a woman who wants to swing on her own, so wants to sleep with a couple,” she explained. “And then a rhino is a single man willing to swing. A mermaid is a married woman willing to swing with a couple on her own, and then rainbow is pretty obvious that they’re happy to swing with everyone and anyone.” Other shorthand includes the term “DDF,” which stands for drug and disease free, and “HMP,” meaning height-weight proportional. These codes allow members to communicate a lot of information quickly and quietly without tipping off those outside the community.
It is worth noting that not everyone wearing a black ring is sending any kind of signal at all. A number of Reddit users and commenters pushed back on the idea that these symbols function as reliable identifiers, with one person writing that “the pineapple was an impulse purchase from HomeGoods” and adding “you’ll be hard pressed to find someone wearing a black ring that is trying to send you a message.” Context, as Lucy and others have pointed out, matters enormously. A black ring on the middle finger, for instance, is more commonly associated with asexuality rather than swinging, so making assumptions without more context could lead to some genuinely awkward interactions. The golden rule, it seems, is not to assume anything based on a single accessory.
So-called “spicy cruises,” sailings specifically organized for lifestyle travelers and the swinging community, have grown in visibility in recent years. These are typically chartered by third-party companies that set their own tone and guidelines, allowing for a more openly adult atmosphere than you would find on a standard family cruise. On regular sailings, public displays remain strictly off-limits regardless of what door decorations or jewelry passengers might be sporting. Whether someone is on a spicy sailing or simply happens to love minimalist accessories, the black ring continues to quietly do its job for those who know what to look for.
The polyamory podcast “Life on the Swingset” has also noted the connection between black rings worn on the right hand and non-monogamy, suggesting the symbol has enough recognition within the community to qualify as a genuine signal, even if it remains ambiguous to outsiders. Pink flamingos and pampas grass are also cited as additional signals used within the same circles, each adding another layer to what has become a surprisingly elaborate visual language. The swinging community’s use of symbols stretches back further than most people realize, with historians tracing early coded identifiers among lifestyle communities to post-World War II suburban America, where the practice first gained significant traction. The upside-down pineapple’s origins as a hospitality symbol, meaning a host is welcoming guests, date back to colonial American times, which makes its repurposing by the swinging community a rather ironic twist on tradition.
