Rumarie was an ancient paganfestival on the planetVulcan that was last observed during the 14th century.
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 Rillan grease, chasing one another." He thought it might be time to bring back the observance, adding that he was thinking of having a Rumarie theme for USS Voyager's mess hall the next week, complete with greasyfoods high in fat and possibly people chasing each other naked.
