A person who lies just to seem smart, even though the other person is clearly way smarter and they're just too proud to say so.
‘I’m the best at everything!’, after losing a game of checkers to a kid in second grade.
‘I know all the secrets of the universe!’, while asking Google how to spell ‘universe.’
‘I’ve been to space!’, when they forgot their homework and ran out of the classroom.
