gender mender
n.
[common] 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 RS232C specification and the distinction between DTE and DCE. Used esp. for RS-232C parts in either the original D-25 or the IBM PC's bogus D-9 format. Also called gender bender, gender blender, sex changer, and even homosexual adapter; however, there appears to be some confusion as to whether a male homosexual adapter has pins on both sides (is doubly male) or sockets on both sides (connects two males).
