What The Joker wants to know.
My father was...a drinker, and one night when he was especially crazy. My mother grabbed a kitchen knife, and daddy didn't like that. No, not at all. He took the knife, and started cutting up her face, laughing the whole time. After he's done, he looks at me and says, "Why so Serious?"

Originally The Joker's "thing" from the new Batman movie The Dark Knight. Ever since it came out idiots and morons alike have been using it non-stop in an attempt to be cool and "edgy".

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.
