Article of clothing worn by women to cover their lady parts 'down there', which is juuuuust big enough to do the job. Can be underwear, swimwear, random item worn during a walk of shame, etc.
An excuse guys or lesbians will use when they're either not interested in a woman or taking a break from women (typically after a break-up).
Implying one is wearing a patch similar to a smoker's nicotine patch.
