DAFEATED
You say it when you beat someone so hard they might start a fight, or you just want to be the loudest person in the room. It’s the sound of someone being extra and not caring who hears it.
DAFEATED when I beat him at chess and he had to sit there in silence.
DAFEATED because my dog beat his dog in the dog show.
DAFEATED when I got the best grade and he got the worst.
