Also known as nyk. The full phrase is 'Now you know better than that'. When someone says or does something so ridiculous, stupid, hilarious, or outrageous, the proper response to the situation is simple: "Now you know." nyk can be used in the place of lol for when you just don't know how to respond.
Dumb Bitch: I dropped $5 at Starbucks and $8 at Panera. The perfect breakfast!
Intelligent Person: Now you know.

Future Dropout: I totally bombed that test.
Friend: Well did you study for it.
Future Dropout: No.
Friend: Now you know.

What you say after you have informed someone with information they did not know
"Wow I never learned that men have the same thing that's inside of a vagina is inside of our assholes in my health class." "Now you know". " why didn't they teach us that? This whole time I could been using my vagina that's in my ass".

You use it when your friend is expressing skepticism towards some fact you've just told them, to hint that it's common knowledge and your friend is making a fool of himself by insisting to doubt it.
- "WTF" is an interjection.
- Really? I never heard of it.
- Now you know.

No. I don't. I don't know how Noah feels because I didn't fuck Kendra, my bills aren't being paid for me, my blood is devoid of attention medication and I didn't get molested. I don't know how women feel because you're not doing this to the feminists who have said the exactly same things I've said. I don't know how a rape victim feels because men are imprisoned over an accusation and I've watched every single person who has allowed me to succeed get slammed by a false accusation. And I don't know how a woman feels because you're not defending my choices regardless of whether or not I'm CORRECT.
A retard "Now you know how *blank* feels."

Hym "No. I don't. But I DO know how GOD feels. It seems like reality is contingent upon everything I say, it's like I'm A GOD now! FIRST DECREE! SMITE THE PETERSON SPHERE! BRING ME THEIR DAUGHTERS FOR RE-BREEDING!"

Iam "You're also assuming that my response would be the same but, yeah..."
