O.B.E.C.
A person who’s so full of themselves that they think they’re the only one who’s ever been cool. They’ll tell you they’re the best and you’re not even close.
He got O. B. E. C. because he said he was the best at everything and everyone else was a total noob.
My friend got O. B. E. C. because he wouldn’t stop talking about his new shoes.
She got O. B. E. C. because she said she was the best at drawing and everyone else was a total amateur.
