What about the British "what" at the end of the sentence, what? Is that now an anachronism, or is it still in use in certain regions or dialects? Or is is more of a Hollywood affectation, what?

I believe it went out with the monocle! But I am ready to be corrected, there may be some recluses in Budleigh Salterton who still use it in between writing to the Times, what, what? Not sure if it was meant to be followed by a question mark, it was strictly rhetorical after all.
