A derogatory term given to someone that has been antagonizing and/or annoying about a subject or opinion but then has subsequently been proven wrong, incorrect or discredited. The term is increasingly damaging when assigned to male. The combination of bitch (noun) a female who is all in all, not pleasant to be around and with stain (noun) a person, place, situation, or anything that exists, but you wish it didn't.
