The act of drinking a large amount of alcohol, and gobbling like a turkey.
Jim drank a whole bottle of Dack Janiels and gobbled loudly and waddled around like a turkey for well over ten minutes. Then soon after, a police officer tasered him, cuffed him, and took him into custody. He's going to do six months community service for his G.U.I. That poor bastard.
