When mean, reckless & bigoted people like Rush Limbaugh order food or drinks in a restaurant, hotel or coffee shop they often receive a "Rush Order" which has the addition of a little special sauce often called "man juice", also known as semen. A "Rush Cup" is often employed to collect this sauce from a group of employees in the public bathroom. This is why you should never, ever abuse a waiter or service person where food or drinks are served.
"Hey, Sean Hannity is here. He's on that damn Blackberry phone again talking way too loud. Lets give him a double Rush Order in his triple non-fat latte."
