The three G's is used as a threat and also as a finishing move for a fight. The three G's gets its name from the 3 moves performed that result in a win for the user. These moves are a Good left, a Good right and Goodnight.
I had a fight with this bloke in the pub the other night. He was giving me abuse so I gave him the three G's
