What differences are typically found between male and female language usage among U.S. middle-class teens?

edit

A recent observations in Paris is that female middle-class US teens seem to use the word 'like' far more than males: e.g. Female: "Like, have you seen, like, the amazing painting in, like, the Louvre, like, they're totally, like, incredible?". Male: "Oh sure, but did you like them!" Female: "Eh, like, did I like them? Like, no!"
