Ning-Nong 

A ning-nong, frequently abbreviated to nong, is someone who has done something stupid or clumsy and has caused a nuisance to others. Although it is can be an insult, it is often used affectionately, especially by Australians.

"Ah Charlie, you're such a ning-nong!" (in reply to a deliberately weak joke.)

Why did you go and invite that ning-nong to our barbecue? He's embarrassing all our guests!

"Stop being such a ning-nong, will you? You're upsetting your sister!
