"Awesome" is a commonplace word of approval here. Young people say it as casually as adult Americans say "good" or a Frenchman would say "bon."

Sample dialogue: (I work in a college post office.)

STUDENT: Can you sell me a stamp?
CLERK (ME): Yes.
STUDENT: Awesome!

I kind of like it. It makes me feel like I'm Superman because I can sell a stamp.

But really, this is trivial. My real problem is that my own son will hardly talk to me at all.
