When a man has sex with a girl on her period, he takes his dick out and rubs it on her lips making it look like The Joker from The Dark Knight. When she gets pissed, ask her "why so serious?"
"Joe gave me The Joker last night, it was disgusting."
"HAHAHAHAHA!!!"
"Thats not funny!!"
"Why so serious?"
"HAHAHAHAHA!!!"
"Thats not funny!!"
"Why so serious?"

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?"

A light hearted insult used by natives of the greater the Chicago area, and thought to be lame by everyone else.
