A colloquial term referring to the action of imbibing a cold, refreshing Genesee beer (Rochester, NY) via shotgun in response to the modern marvel at Tight End, Brandon Pettigrew, scoring more than 5pts in Fantasy Football in a single game.

Important note: This action requires another party to be a witness. If alone, a recording of the Shotgrew must be made and sent to said additional party.
Man 1: "Shit, The Grew scored a TD."

Man 2: "Gee Man 1, I guess it's time for you to Shotgrew."
