Octopused
when you brag about yourself like you're the best person ever. You think you're awesome and you tell everyone how awesome you are. You're like an octopus with eight arms all patting themselves on the back.
I got an A on the test and I told everyone I was the best.
I beat my brother at video games and I said I was the greatest.
I got a promotion and I bragged about it nonstop.
