Héctor Salamanca is a former Juárez cartel enforcer in Breaking Bad, later explored in depth in the prequel Better Call Saul, who communicates almost entirely by ringing the small bell mounted on his wheelchair. The sound became instantly recognisable because the show uses it sparingly, often for a yes, a warning, or a threat, and fans began clipping it for reaction videos and edits. It endures as shorthand for silent menace, letting a single ding carry the weight of his character without a line of dialogue.
