What is Ground Rule Double?
1.
Copping a feel on a girl without ever making out. Most commonly occurs at parties or dance clubs. Named for the circumstance in baseball when a player hits a ball and it bounces over the wall. He automatically advances to second base.
Person 1: Dude, did you see me grabbing that girl's tit when we were dancing? I totally just got to second base in like 5 minutes.
Person 2: I'm not sure if that qualifies as second base. It's more like a ground rule double.

Variation on upper decker. Instead of shitting in the tank of a toilet, shitting in the bowl and then manually repositioning the load to the tank.
I was so drunk I forgot to do an upper decker, but after I saw the sweet log I fired into the bowl I knew I had to go for the ground rule double.
