Best

In Nigeria instead of saying something is your favorite you instead say it is your best. So instead of "what is your favorite movie?" it would be "what is your best movie?" Or instead of "Lady GaGa is my favorite singer" you would say "Lady GaGa is my best singer." I always thought it was the funniest strange expression and it always made me chuckle a little on the inside. But the other day I realized in the US we use the same expression in at least one way. You wouldn't say "My favorite friend is Ange" you would say "My best friend is Ange." So now it doesn't seem as strange, but I have to admit, I still giggle a little on the inside every time I hear it.
