In criminal trial work I termed it a “boomerang strategy” and used it against opponents.
From CNN:
Republicans are masters of verbal jiu-jitsu. It’s a form of linguistic combat in which the practitioner takes a political phrase or concept popularized by their opponent and gradually turns into an unusable slur. Like the Japanese martial art known as jiu-jitsu, its devotees avoid taking opposing arguments head on and instead redirect their opponents’ momentum to beat them.
Mention almost any touchstone phrase adopted by the left in recent years — “critical race theory,” “diversity,” “global warming,” even the word “liberal” itself — and it has been redefined or tarnished by conservatives.
