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, raise your right leg high, then bring it down from outside, behind, and above your opponent’s right leg, so that it descends against his thigh as a brace that breaks his balance and causes him to fall.
