The cue black out in a light plot means that every light on the stage is switched off. In revue a black out serves as a quick curtain to a sketch. It often cloaks the lowering of a front cloth for the next item, which may be some lively patter by the comedian whilst the next set is being erected behind the cloth. (2) To forget one's lines in a mental black-out.
