大外落 O-soto-otoshi (large outer drop) OSO

A foot technique throw. Nearly identical to o-soto-gari (large outer reap) and difficult to distinguish from it. Instead of reaping your opponent’s leg, however, rise your right leg high then bring it down from outside, behind, and above your opponent’s right leg, so that it descends against his tight as a brace that break his balance and causes him to fall.
