Quoi?

My boyfriend calls me Quoi, wich if french for What?, because I say What? or Huh? a lot. So anytime he says my nickname. I say 'What?' and he says Quoi. And it turns into an English Vs. French battle. Until one of us say the wrong word. It's funny, and some times other people join in too, and saying What in a different languae too.
Examples: German- Was?
Italian- Cosa?
Norwegain- Hva? (pronouced var)
Polish- Co? (tsa)
Those are just some examples. Of words we use to start these language battles. We also call the people that say the certain words by there what words too. Hope you think this is a good idea.
