G.T.I.Y.
A loud shout that tells people to stop being ridiculous and just get over it.
My dog barked at a shadow for 15 minutes. I yelled G. T. I. Y. and he stopped.
My friend got mad because his pencil broke. I said G. T. I. Y. and he threw it.
My mom got angry because the coffee was too hot. I told her G. T. I. Y. and she drank it.
