Time for ... math class? A square root is sex position (apparently made-up as a joke) that involves four people lying on their sides, forming a square shape as they perform oral sex on each other. It puns on the Australia slang root, or "have sex," and the mathematical square root. In math, a square root refers to a number that multiplies itself to get another number, e.g., 8 x 8 = 64, making 8 the square root of 64. But not even this is safe from all sorts of sex jokes.
