Grandfather clause 

When a patron that isn't of legal drinking age enters an establishment before it transitions from restaurant status to bar/club status thus bypassing ID checks at the door.

Geoff: "Grant, let's all go celebrate your birthday at that new establishment and get you really drunk so your girlfriend can take full advantage of you."
Grant: "But my girlfriend isn't legal drinking age yet."
Geoff: "No worries, lets get there early and she can use the grandfather clause."
Grant: "That seems appropriate."
Kris: "People do that."
Nicole: "That makes sense."
Geoff: "I'm sure there's no science to support that."

Grandfather Clock

The grandfather clock is performed while suspended in the air, generally with the help of 2 others. It is when you are hovering above a sleeping persons face with your dick and/or balls hanging directly over their face, waking them with either a slap or a loud noise (preferably similar to a grandfather clock striking the hour).

Dude, Robb ba ba brain'd me, so I'm gonna get him back tonight with a grandfather clock.

Grandfather Clock

When you are down to your “reserve” pair underwear or boxer shorts that have a hole in the bottom exposing your dick hanging down simulation a working grandfather clock.

When I was wearing my old boxer shorts I walked out in front of my girlfriend and she said nice grandfather clock.
