throw a 7

To die or stop living. In the dice game of craps, a shooter "craps out" when they roll a seven and all bets are cleared from the table. The end of someone's life. Past tense would be "threw a seven".

Bill: "How is your grandma doing these days?"
John: "Well she is sick now and grandpa is concerned that she might throw a 7..."
