The Tradesman's definitions
A person playing Craps for the first time, who amazingly stays on the same roll for 45 minutes straight or longer, winning loads of money in the process.
"It had been 20 minutes without a losing roll of the dice, and people all over the casino came to watch the potential grey roller, a once in a lifetime sight in casinos.
