This is an extremely painful event. It typically occurs in the stock market, when you just finished getting so leveraged up on full margin with
short positions.
The stock market then viciously turns and "heads" up the other direction all while ripping your
face physically off. It happens so quickly it is typically only noticed when you look up from your
keyboard to ask your trading partner what happened, and he only see's a pair of lips and what used to resemble a
face talking to him.
