A McAmbush is when a fast food restaurant is swamped by an order containing an insane number of cheap sandwiches. This order is placed because the customer wants to obstruct the drive-thru for as long as possible and have the employees make a lot of sandwiches without having to pay a lot of money.
Charlie pissed off the fast-food employees because his McAmbush consisted of 100 cheeseburgers from the dollar menu.
