Dunderbee 

A dunderbee is a person who is a fascinated by travel and knows almost everything about other cultures. A true dunderbee has visited all 7 continent and has been to at least 75 countries in his/her lifetime. However, dunderbee is not someone that will rattle off information that nobody cares about just to show off; he is a true people's person and uses only the interesting details of his travels to impress people. In short, a dunderbee is to travel as a shutterbug is to photography.

Dunderbee: Did you know that I've been to every country in Europe?
Guy 1: Wow, you're a real dunderbee!!

dunderbunny

Someone that just can't seem to do anything right. So much so that everything they touch turns to shit. See also clod or dimwit.

Byron: Everything he touches just falls apart. It's almost like the poor dolt is cursed.
Tobias: yup. He's a dunderbunny like you read about. Stupid hamfist!
