A piece of tissue or cloth stuck to a wound to stop bleeding. A bachelor band-aid is usually used when a person can't afford band-aids or is too lazy to get any.
Person 1: "I'm bleeding!"
Person 2: "Well, I don't have any band-aids. You'll just have to use this paper towel bachelor band-aid for now. Try not to get blood on the carpet."
