G.S.A.L.O.
G. S. A. L. O. is when you tell someone to go stick their face in a toilet. It’s a fancy way of telling them to be quiet.
At lunch, my friend kept talking and I said, 'G. S. A. L. O.!' and he went quiet.
My little sister wouldn’t stop crying and I said, 'G. S. A. L. O.!' and she stopped.
My neighbor yelled at me and I said, 'G. S. A. L. O.!' and he went away.
