Flag
Pointing the muzzle at a person or thing you do not intend to shoot.
Also: muzzle, muzzling, sweep
To flag someone is to let your muzzle pass over them — a violation of rule two of the four rules. Muzzling and sweeping are synonyms. Flagging is the most common immediate-correction offense at any range, and the reason instructors fixate on muzzle awareness during draws, reloads, and reholstering.
