CBMP (contra-body movement position) is a foot position in which the moving foot goes on or across the path of the other foot. One result is that it puts the body in (approximately) the same orientation relative to the feet as CBM (contra-body movement)--this is probably the reason for the name. Guy Howard's (IDTA) book says "The placing of the stepping foot, forward or back, onto or across the line of the other foot, giving the appearance of CBM having been used, but without turning the body."
