Deriving it's name from "Spitroasting," the Utah Barbecue is a similar sex act, where a woman is placed doggy style and is penetrated both orally and vaginally, by two men. The difference being that another woman lays on top of the first, facing the opposite direction, allowing the men to switch between oral and
vaginal sex at their own discretion.
By extension, 2 optional elements can be implemented
1: the two men HAVE to stare into each others eyes, as a way to poke fun at the repressed
homosexuality in the Utah/Mormon communities.
2: The women are not allowed to talk, move, or complain about the situation, poking fun at the misogyny in the Utah/Mormon communities.
Ideally, the two men and women are a pair of straight couples, which is why the name is so specific, as the it is supposed to conjure up a classic Utahn Block Party, but except with a spit roast, rather than a grill.
