The result of the new double drive-through design many fast food restaurants (namely McDonalds) are using. Two lanes converge into one in what should be an orderly fashion...until, that is, when people are in too much of a hurry to understand the concept and start cutting each other off, creating mass confusion for the customers and the staff.
"I would have been here earlier but I ran into a giant McClusterfuck at the drive-through AND got the wrong order on top of it!"
