Chapete is a slang term that literally refers to a rosy cheek or blush. However, in the context of this song, it's used in a much darker and more menacing way.
Santa Fe Klan uses it to refer to someone who is naive or inexperienced, often implying they are about to face a harsh reality. When he says, "Aquí te cae la muerte, mendigo chapete," he's warning a naive individual that death awaits them in his neighborhood, highlighting the dangerous environment he describes.
