Hey! Look at Grandpa Beefcake and his son over there hitting up those spring breakers drunk on hard seltzer at the pool.

Sad grandpa is to be said when anyone is getting ready to change. It is a sign to all other people in the room that clothes are getting ready to fly, and to close all doors and to look away if you don't want to see "the goods."
Hey guys I gotta get ready for practice... sad grandpa.
Alright man, I'll get the door on the way out.

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.
