Habadoo
A magic word that makes everyone shut up and stop laughing like a bunch of monkeys on crack. You yell it when the noise is so loud it could wake the dead.
"Habadoo!" I screamed. The whole class froze like a bunch of傻x.
During the principal's speech, I yelled "Habadoo!" and the chaos stopped like magic.
At the party, I shouted "Habadoo!" and everyone shut up like they were told by God.
