A person who tries to act like a nerd and refuses to accept the fact that he/she is not smart.
Eugene: It is just so annoyingly distressing that Jake displays this pretentious act to delude others to beleive he is what he is not--a classic, certified nerd.

Both: (snickering and snorting in a nerdy manner.)
