gender mender
     
         (Or "gender bender", "gender blender", "sex
        changer", and even "homosexual adaptor") A cable connector
        shell with either two male or two female connectors on it,
        used to correct the mismatches that result when some {loser}
        didn't understand the {EIA-232C} specification and the
        distinction between {DTE} and {DCE}.  Used especially for
        EIA-232C parts in either the original {D-25} or the {IBM PC}'s
        {D-9} connector.
     
        There appears to be some confusion as to whether a "male
        homosexual adaptor" has pins on both sides (is doubly male) or
        sockets on both sides (connects two males).
