A dogwhistle is a coded message meant to be understood by a specific group while seeming harmless to others. Like a whistle only dogs hear, it's hidden in plain sight. In psyops, gestures like coughing, a hand sign, or a certain outfit can act as dogwhistles—signaling others to act or triggering a target's awareness. These cues double as both messages to insiders and psychological triggers to the intended subject.
