Bibby doof gumper

By day, a bibby doof gumper is an ordinary, everyday Navy officer. By night, however, he is a hella evil terrorist who will stop at nothing to destroy America

Me: Hey dude, you seem to be a normal individual who is definitely not a terrorist at all
You: O, that's cool. By the way, America totally sucks.
Me: Dude, you're a "bibby doof gumper"
