Termites: they chew up the courses. This refers to the shirtless punk fratboy types throwing their discs with other peoples names inked on them. Drinking cheap beer and being generally disrespectful. Termites.
However, some posts mentioned families throwing or one discers. I love seeing families out. Just skip around them. No biggie. One discers likewise. They don't pose a problem. If a dude is throwing multiple shots, so what? Play through. Go around. Whatever. Your casual round and theirs are the same. It must be tough to throw 500 feet from your high horse.
