Arm triangle choke, side choke, or head and arm choke are generic terms describing blood chokeholds in which the opponent is strangled in between their own shoulder and the practitioner's arm. This is as opposed to the regular triangle choke, which denotes a chokehold using the legs, albeit with a similar mechanism of strangulation against the opponent's own shoulder.
