The flying armbar is a version of the juji-gatame that is performed from a stand-up position. Without a gi, it is typically applied when the opponent has a collar tie. By tightly holding the opponent's neck and arm, the attacker puts one of his or their shins against the opponents midsection, and leans up on the opponent; at the same time, the attacker swings the leg on the same side as the opponent's collar tie over the opponents head, into the typical juji-gatame position. (With a gi, it can be performed without needing to hold the neck.) If improperly performed, this technique will cause the opponent to escape the hold and gain an advantageous position, even the option of slamming the attacker to the ground. The flying armbar is considered to be one of the most spectacular joint locks, but it is uncommon because of the risk of losing position.
