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.
1) Wow, Dana was being such a bitch-stain, and wouldn’t stop whining about all the work he did when I actually did half of it for him!

Get the bitch-stain mug.
A term used for an ex-girlfriend that was a complete bitch and still wont leave you alone (whether by being a clingy ex, hurting your reputation, or if she was just a bitchy girlfriend all together).
Example 1: Person A: So last night at the party my ex got drunk and told everyone she gave me herpes, while I was talkin with Stacey!

Person B: Damn, what a bitch-stain!

Example 2: Person A: Shit, she needs to leave me alone! We broke up two weeks ago!

Person B: Damn, what a bitch-stain!

Example 3: Person A: My girl got mad at me because I hung out with ya'll after the both of us were together for six hours straight!

Person B: Damn, make her your bitch-stain!

Get the Bitch-stain mug.
A girl that has been fucked to much, worn out like an old stained jumper that no one wants... Like a wannabe Milf, you know the sort old bird thinks she can still go out every week and looks like shit in a microwave.
"Look at that old stained bitch"

"What a fucking mess"

"Yeah what a fucking stained bitch"

"I wouldn't wipe my ass off in her face"
