Most of our trash talk is pretty personalized. We occasionally say the stuff like “bring a shovel” (in sand).
When a guy leaves any kind of par or better putt short, we go into the Family Guy’s Stewie; “Mommy, momma, momma, Mom, Louis”.
We play a game called Snake that involves not wanting to 3-putt. If a guy is on the green but far away we just hiss at him incessantly.
One of our normal golf buddies crushes the ball. When he occasionally gets out-driven by one of us we continually ask him where his ball is. "Where's your ball man? Is it up with mine? I can't find it. It must be well after mine right?"
At one point, a guy who hits long for some reason decided to hit his 5 iron on a 145 yard Par 3. We didn't know he did this so right after impact we said, "looks nice, what did you hit?" When he responded "a soft 5", I said "I take it back. That's a terrible shot". Now, anytime he hits a pretty shot its "nice shot. Soft 5?", even if it's obviously his driver.
When we were younger, and very stupid, we used to “Terry Tate” each other. Randomly after a nice drive, if the guy held his pose a bit too long, one of our buddies who played 1AA football would just form tackle the guy in his pose.
