When a person in a sport, usually golf, makes a bad shot that they personally think is awesome. Others around them, or sometimes even the one who made the shot, are to yell, "Yolk stick!" In most cases it is said in a goofy tone and the "o" in yolk is held, along with the "i" in stick so it is pronounced, "Yooolk stiiiiiiick!"
Golfer one: "I'm gonna drive this to the green!" *Hits ball with a nasty right hook and still goes far*
Golfer two: "Yooolk stiiiiiiick!"
Golfer one: "Ya right, that is a yolk stick."
Golfer two: "Yooolk stiiiiiiick!"
