Ducking up the finish

Celebrating before actually crossing the finish line/goal line; resulting in an embarrassing loss or inability to score on what should be an easy score.

Man, the University of Oregon keeps ducking up the finish. Did you see that University of Oregon runner start celebrating before he crossed the finish line. He ended up losing to another runner because he was celebrating before he had actually won the race.

Upper Decking 

Deficating in the tank of someone's toilet, rather than the bowl. Often employed in malicious context.

Suzy could not figure out why her toiled would flush only brown water. Little did she know that Johnny had upper decked that bitch the previous night.
