when a man has sex with a woman on her period. He pulls his dick out and smacks it across her mouth and says "Why so Serious?"
jack went up to his buddy john and said "man, me and jill were doin it earlier and she didn'tell me she was on her period." john looked up at him and asked "so what'd you do when you found out?" "well," jack said, "i looked at here dead in the eyes and pulled the joker on her."

While having sex you finger the girls ass and make sure to get her poo on your finger. When ready, you pull out (before during or after cumming as it does not matter.) and smear her poo from one cheek, across her lips to the other cheek. When she gets mad at you, simply ask "Why So Serious?".
I gave her the joker last night. After I smeared her poo from one cheek to the other via the lips she got all mad at me. So I asked her "Why so serious?"

First off, take a girls virginity. When she starts to bleed, get some blood on your fingers and smear it around your mouth from cheek to cheek. When she starts to cry or look disgusted, yell out "Why so serious?!"
Jenny started to bleed from the vagina, because it was her first time having sex. John then began to smear her blood all around his mouth from cheek to cheek, pretending to be the joker. As Jenny started to cry, John then proceeds to yell out "Why so serious?!"

The Joker is a sexual maneuver performed by a man having sex with a woman on her period. The man sticks two fingers into her pussy and then inserts his bloodied fingers into her mouth, thus giving her a bloody smile a la The Joker. When she turns around to angrily ask what he's doing, he exclaims, "WHY SO SERIOUS???"
Chris told me that he pulled off The Joker last night. That explains why his girlfriend is so upset!
