Pache
A pach is a messed-up way of saying Papa Burger with Cheese. It's what cooks use to talk to cashiers and make sure they don't mess up the order.
"Pach, please! I want two of those!", The cook, yelling at the cashier
"Why did you say pach instead of Papa Burger with Cheese?", The customer
"Pach, pach, pach!", The whole kitchen, during rush hour"
