A generalized comeback when someone suggests for you to do something. Especially when said something is:
a) obvious
b) your job but you'd rather it not be

Most effectively used when your friend is right but you don't want to give them the gratification of admitting as much.
Friend1: "I really like this girl but I don't know what to do."
Friend2: "Why don't you just ask her out?"
Friend1: "Why don't you?"

The command used by Chris Hansen, of Dateline NBC, before publicly humiliating and destroying would be child molestors on national television. No matter how much the child molestor wants to run, for reasons unknown to man, he cannot leave and always takes a seat.
Chris Hansen: Why don't you have a seat?
Child Molestor: Oh shit! I swear I wasn't going to do anything with that 13 year old boy. I have to go now!
Chris Hansen: Why don't you have a seat right over there.
Child Molestor can't help himself, and has a seat.

The dreaded words that Chris Hansen will tell you when you go into the house hoping to hook up with an underage girl.
I walked into the house
"hey did you bring the stuff I asked for?"
"Smirnoff Ice and strawberry condoms, you bet."
"ok let me just get changed"
I go into the kitchen and see Chris Hansen
"why don't you take a seat"

The proper response to any question in the form of: "Why don't you (do something you don't want to do)?"

"Why don't you just make a pizza?"

No seriously. This is a reference to Breaking Bad season 1 episode 4, when Walter Junior, upset and in turmoil over his father's lung cancer diagnosis, outrages at his farther's hopelessness. His mother, Skyler White, is visibly distraught and in shock. Walter White, his father, is facially ambiguous, but I suggest that he is turned on by the unexpected lash out. The abruptness and out-of-pocketness makes this one of the funniest lines in Breaking Bad, nay, in American television.

The writers could well have ended the entire TV show by having Walter White die right then and there and rolling the credits. In fact, this would have been a totally viable ending to a long-winded story and would have prevented the rise of the crack-addicted, mentally unstable Breaking Bad community. Just imagine a world free from crack-heads yelling "JESSE WAKE UP" in public.

The phrase is most often unintentionally used by rage-quitting gamers; specifically, Minecraft zealots when they have two hearts, no shield, and three skeletons are raping them. The phrase also features in many political debates when the opposition runs out of rebuttals and resorts to crude insults, because, after all, this is the best way to assert yourself in discourse.

A more defiant way of saying fuck off, typically used for emphasis or to sound like the smartass you're saying it to.
