On my local (est) course there are tons of them. My wife's friends are the worst. They show up, 12 people and 2 dogs deep with 8 kids out of that 12 people and a baby stroller. They just take over the course throwing their Bosses and putting with Vulcan's and just generally being obnoxious. We just call them chuckers. And to their faces. Ive confronted them about it numerous times...I swear to God one time the big fat lady of the group says "You think because you play in tournaments that everyone should take this so seriously."
Whatever. As long as they are having fun, I guess.
Luckily if I go down the road another 5 miles, we have a lot longer and lot more challenging course. The first time I played there, I asked some locals if the course had problems with chuckers. They had no idea what I was talking about. So I prefer that course, for sure.
The moat annoying thing chuckers do? On a longer hole, they'll pick up your drive and be like " oh, is this yours? Sweet throw dude!" And throw it back to you! Happened to my playing partner today. Luckily he is much cooler-headed than I am.
