When you climax on a girls face and rub your penis across her lips and cheeks in the shape of a smile. The lipstick and the sperm should mix together forming a joker like appearance. After this you take a look at your makeup art and ask her the question "Why So Serious?"
I was having sex with a girl last night. I finished her off with a Why So Serious?

Get the Why So Serious? mug.
The act of smearing your menstrual-blood covered dick all over your girlfriends' face, so as to make her appear to be wearing The Joker's classic make-up.
The other night my lady was on the rag, but I managed to talk her into a "Why So Serious?" session!

First off, this is used mostly by emo kids who use it for a picture caption on their myspace. People who say it don't realize how annoying it is. Also, asking "why so cereal?" deserves a punch. Just wait until another movie comes out then steal shit from there too!

Get the why so serious mug.
a line use by a convicted murderer in Sweden, who painted it on the bathroom where he killed his victim.

but if its a man is not clear as the convicted murderer has a "personal id" that only woman gets when they are born in this country. at least it used to be that way, afaik.

after the murder they had a investigation about the persons psysical health and it said that he was found "psychiacly good shape" or whatever you call it in english, a big joke imo.
