The internet has a way of unearthing niche knowledge that can leave the general public both informed and deeply unsettled. The latest term to cause such a reaction is “Roman shower,” a phrase that has recently sent people searching for definitions and then regretting their curiosity. Contrary to any assumptions about hygiene or historical self-care, the term refers to a consensual sexual act where one participant vomits on the other.
The discovery has triggered a torrent of horrified reactions online. On forums dedicated to sexual wellness and curiosity, users have expressed everything from stunned disbelief to firm dismissal. Many have commented that the practice falls far outside their personal boundaries, with several noting that the experience of vomiting is unpleasant enough when one is ill, making the idea of engaging in it for arousal entirely unappealing. The general sentiment is that this is one form of exploration they are happy to forgo.

The nomenclature, however, is a fascinating case of history being misremembered and repurposed. The “Roman” in “Roman shower” is a direct reference to the enduring but false myth of the Roman vomitorium. According to this popular legend, which has been passed down for centuries, elite Romans would participate in feasts of such excess that they needed to vomit intentionally in a special room to make room for more food. This story has been used as a prime example of ancient moral decay and overindulgence.
In truth, the vomitorium was an exit passage, not a purging room. These were the large tunnels in amphitheaters designed to allow a massive flow of people to exit quickly, “vomiting” them out into the surrounding areas. The theatrical industry still sometimes uses the term “voms” for quick stage exits today. Historians have worked diligently to correct the record, but the powerful and grotesque image of Romans purging for pleasure has remained embedded in popular culture.
This lingering myth provided the perfect, albeit inaccurate, label for the fetish. By naming it a “Roman shower,” the practice is symbolically linked to that same idea of extreme, transgressive decadence. For the countless people who are just now learning about it, the experience is a double revelation: first, the shock of the act itself, and second, a mini-history lesson about how a centuries-old misconception can find a bizarre new life in the modern world, leaving everyone a little more horrified and a little more knowledgeable.
