kevin Fabs:I don't know...I'm the grandpa master.

grandpa on the shitter 

This is the instance whenever one is playing golf and attempts to hit the ball over a water hazard and ends up not clearing the hazard with the first attempt, which would require a second attempt with a one stoke penalty. If the second shot fails to clear the hazard it is known as a "Grandpa on the shitter". Reason: two balls in the water.

Jason couldn't carry the water on the 17th hole twice, so he lost the hole AND the match with a Grandpa on the shitter.
