How about print this on the back of each ticket:
Due to the recent increase in unruly shouting, particularly after tee shots, such outburts are now expressly forbidden and will result in your removal without refund. These outburts detract from the grace and finesse of the game of golf. Examples of such outburts are, but are not limited to, the following:
"You 'da Man"
"Get in the Hole"
"Mashed Potatoes" (or any food-related phrase such as "Fried Chicken", "Beef Stew", etc)
"Light The Candle"
"Yabba Dabba Doo"
To ensure a safe and enjoyable environment for all, please only say the following golf-related phrases in a normal speaking volume:
"Good one" or "Way to Go" (spectators choice).
Thanks for your continued patronage and support of the PGA Tour.
