Rumarie

From Memory Alpha, the free Star Trek reference

Rumarie was an ancient pagan holiday on the planet Vulcan that was last observed during the 14th century AD.

In 2372, while learning about Vulcan holidays, Neelix discovered Rumarie, which he described as a festival "full of barely clothed Vulcan men and women, covered in slippery Rillian grease, chasing one another." (VOY: "Meld")
