McDickHead
A guy who can't decide what he wants to eat at McDonald's and holds up the whole line. Then when he finally decides what he wants, he doesn't have enough money to pay for it and turns around and asks you for change. Then he changes his order and orders with extra pickles, no onions, extra salt, no sesame seeds, and a well cooked burger. Then he spills his order all over and demands a free one.
Man I was at McD's and there was this real McDickHead there holding up the line.
