We were just talking about that earlier in the office. It probably was funny the first time someone said it but come on! Par 5 driver and the guys yells "in the hole!"
geez LOL
I think they do it as a joke at this point.
I heard someone say get in the hole on the 670 yard par 5 tee shot.
You have to think the people saying there are doing it just for fun and do not mean it literally.
