Golfing on any golf course while ignoring most of the rules and etiquette of the sport. While Street Golfing players will most likely not keep score, chew tobacco, drink a lot, piss a lot, drive carts into woods looking for golf balls and get stuck, and do what ever the hell they want. If a player does not like their shot they will just drop another ball and play that one. A golf course will never appreciate a Street Golfer because basically they ruin the sport for people who A) are good and wish to remain uninterupted, or B) not good and are bitches about everything.
Frank: Lets go play some Street Golf.
Me: ...why not, nothing better to do.
