Don't get me wrong. I'm very happy with 'Would you get me the weather for Goose Bay, please?', but anything below FL100 or so should not involve words not written in the Ops Manual. Have you ever read a CVR transcript from an incident/accident, and thought 'why all the non-operationally-necessary words and phrases?'. That is reason enough to stick to what's in the book. No more, no less.
PS, check your dictionary. I'm not being anachronistic.
