Stupid words creeping into our language No.1

Closure: the act of closing; the state of being closed; a bringing to an end; conclusion.

Such an American word that you hear more and more of these days, especially in the media. People, we don't live in an episode of Friends or Greys Anatomy, so lets not try to talk like we do. Why not use such far out words instead as: conclusion, end, draw a line under, finish or bring to a close.
It's, like, so much, like, more natural!
