The Grandwich 

A sandwich that contains all aspects of a large dinner.
For instance: With a roast/Sunday dinner, one may put mashed potato, carrots, roast potato, chicken (or whatever meat you have) and possibly a Yorkshire pudding.
The kinds of Grandwiches are endless.

Bill: Man, I just chowed down on the most epic Grandwich!
Bob: ... Grandwich?
Bill: Yeah! The sandwich of all aspects; The Grandwich! It is legion, it does not forgive, it does not forget. Expect it.

Glen Allen Grantwich 

When you are watching Football (Usually the JMU Dukes) with your home boyz from Glen Allen and decide to set up a slip n slide. Since it’s the Richmond metro area, the only thing you have to put on it to help slide is pimento cheese and northern neck ginger ale. The resulting greasy man pile at the end is a Grantwich

Grantford: let’s set up the slip n slide out back.
Richardo: I’ll grab the pimento cheese and this northern neck gingerale to lube it with.
Home boyz: weeeeee!!!!! (Crashing and piling up at the end shirtless and greasy)
Grantford: This is the best Glen Allen Grantwich we’ve ever made!!!!
