A very popular tagline for the movie "The Dark Knight". The phrase has achieved a level of popularity, earning it spots as an internet meme, several XBOX Live account names, and something for 13 year olds to put in their signatures on forums to be scary and angsty.

By the year 2018, this will be the new "Where's the Beef?!"
20 Years After the Dark Knight...

Person 1: Remember that dumbass who got "why so serious?" tattooed on his shoulder?

Person 2: Yeah, what a dork.

The most popular phrase from "The Dark Knight". used by fanboys and the genuinely joker-like characters alike. Although its a cool thing to say, say it to much and someone may punch you in the face.

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?

In reference to the Joker in Batman, "Why so serious?" is a phrase for somebody to use who is openly stating that they are wearing excess amounts of makeup.
Yeah, I know. Why so serious?

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!
