Historically, a “grease devil” was a thief who wore only underwear or went naked and covered his body in grease to make himself difficult to grab if chased.
Según la historia, un “demonio engrasado” era un ladrón que usaba sólo ropa interior o andaba desnudo y cubría su cuerpo entero con grasa para hacerse difícil de atrapar si lo perseguían.
