DAFEATED
You yell it when you beat someone so bad they’re probably jealous, or you just want to show off. It’s like screaming ‘I’m the best’ in a very loud and annoying way.
DAFEATED when I won the spelling bee and he forgot how to spell ‘cat’.
DAFEATED because I got the last slice of pizza.
DAFEATED when I beat him in the talent show and he had to sing in front of the whole school.
