A character from the comedic film, "Monty Python and The Holy Grail." In the movie, this comedy relief in what was already an obvious comedy spars with King Arthur of Britain and somehow ends up missing all his limbs, yet still alive (and proceeds to taunt King Arthur) This character is widely parodied and in fact, has merchandise that can be found in video stores worldwide commemorating his madness.

When a guy rides a bike over to a girl's house, fucks her in the ass, and then rides his bike immediately home. (Inspired by Drama from the episode of Entourage when he says he fucked a chick in the ass and then made her ride her bike home.)
Person A: Dude, you'll never believe what I did last night.

Person B: What?

Person A: I Black Knighted Sara!

Person B: Wow, that's awesome! I've never successfully pulled off The Black Knight.

An anti-feminist. A White Knight´s natural enemy who on the contrary will defend any woman just because she is a woman regardless if she is right or wrong.
Black Knight: That bitch kicked the poor boy with no reason! I´m going to kick her now.
White Knight: No sir, I won´t let you...
Black Knight: Fuck you, I will kick you too!

In contrast to a White Knight, a Black Knight is any one person who- rather than frantically defending women who are being badgered by men on the internet- is always attacking women who are badgering men.

While images abound of evil black knights rampaging the countryside, these tales are far from the truth. A black knight is a knight not sponsored or employed by a local lord for the defense of his lands. Therefore, the black knight does not have at his disposal the resources needed to keep his armor polished and in good repair. To save face, these knights painted their armor black, to hide any wear and tear that the armor may have endured.
The black knight knelt before the Duke, hoping to end his long bout of unemployment.

In Korean 흑기사 ("Black Knight"), this word would mean someone (generally a guy) who volunteers to take a drink for another person (generally a girl). For a man it’s 흑기사 (heuk-gi-sa, “dark knight”) or 흑장미 (heuk-jang-mi, “black rose”) for women. One can ask someone to be their black knight/rose, or someone can offer to do it, but once you’ve done it, you’re theirs for the rest of the night. If you ask someone and they refuse, then you have to take two drinks.
While playing a drinking game, a girl has had too much to drink but has to take a shot. She can then call out for a Black Knight or Dark Knight and a generous guy may take the drink for her.
