Clearly one of the greatest adverbs in the English language. Can be used at the start or
tacked onto the end of absolutely any - and I mean ANY - sentence for emphasis, adding that extra-special pretentious feeling that one desires in one's speech. Used particularly when the speaker would like to make the person being addressed feel
that what is being said is purely
common knowledge and that they are utterly retarded for not already knowing it or for disagreeing with it.
