In bridge, used to describe any bid which has some conventional meaning that doesn't indicate strength in the suit named. For example, if playing the weak two bid convention, opening bids of 2D, 2H, and 2S are used to indicate weak (below usual opening strength) hands with 6 or more cards in the suit named, while 2C is a strong artificial bid used to indicate any hand with 22 or more high card points. (As opposed to the strong two bid convention, in which all the 2-level opening bids represent strong hands with length in the suit named.)
