A sexual act in which two girls mimic the time honored tradition of the wining hockey team drinking champagne out of the Stanley Cup, by inverting a male participant with his legs spread wide, thus creating a cup out of his anal orifice from which they will then urinate into and then drink out of, sometimes with a straw.
"Those girls roll dirty, I heard they like to perform the two girls, one stanley cup"
