Leg-and-arm triangle

Leg-and-arm triangle is the descriptive name for the buggy choke — the strangle from bottom side control in which one side of the neck is closed by the attacker’s leg and the other by the defender’s own trapped shoulder.

Etymology. The descriptive form says what the technique’s own name does not. Buggy is a coined label with no mechanical content; naming the two mechanics it hybridises tells a grappler immediately what the structure is and, more usefully, why it fails when it fails.

Mechanics. The attacker turns onto their side beneath side control, elevates the top leg over the opponent’s head and neck, and threads their own top-side arm deep behind their own knee — to the back of the knee, not the shin. The opponent’s head and near arm are enclosed together; the legs figure-four and a gable or palm-to-palm grip closes the frame. Every contact point is the attacker holding their own body, which is why the structure survives the opponent fighting it. The finish squeezes the arms, crunches the torso and lat inward, and drives the legs down, compressing both carotids.

The arm is half the choke. A buggy choke that encloses the head without the near arm has one surface on one side of the neck, which produces discomfort rather than a strangle — the same requirement that governs the arm triangle, and the most common reason first attempts produce nothing.

Cross-reference. The triangle supplies the leg mechanic and the arm triangle the head-and-arm one. Full mechanical coverage on Buggy Choke.
