The term 'SHOCK WITH A STUN GUN' can be summarized by the four-letter word 'TASE'. TASE is an acronym for 'Thomas A. Swift's Electric Rifle', which is a type of stun gun used by law enforcement officers to temporarily incapacitate a person. It works by delivering an electric shock to the target, causing them to become momentarily paralyzed. The use of stun guns has become increasingly popular in recent years as a non-lethal alternative to firearms.
