Gahoi
A fancy way to tell someone to shut up. It’s like screaming ‘get a grip’ but with more letters and less sense.
My mom yelled at me, ‘GAHOY!’ when I spilled juice on the floor for the third time.
My friend said ‘GAHOY’ when I started crying over a broken pencil.
I told my teacher ‘gahoy’ when she gave me 10 extra homework sheets.
