Also known as the McFrag. This is when you order a shake of any size and flavor with no straw, and take the lid of as if you were going to take a sip. You then proceed to yell FIRE IN THE HOLE, and chuck it back into the the window at the person and drive off.
THIS MUST BE DONE AT THE DRIVE THROUGH OR YOU WILL RISK BEING CAUGHT!
