bladed stance
n.— «I’m not a cop, but a bladed stance is where, rather than being directly lined up and with both feet the same distance from who you’re facing, your body is angled with one foot further away than the other. One reason some people in higher-risk situations do that is to be in a more stable stance to keep from being knocked on their ass if the person they’re addressing decides to attack them.» —“”are You A Cop?” And Other Tales” by wrffr Volokh Conspiracy Dec. 17, 2007.
