Now you know

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.

If you know what I mean

Usually added to a sentence that makes absolutely no since but makes it sound like its a common phrase. Over all makes everyone really confused.

I too like to shake a bag of old wrenches if you know what I mean.

you know why.

This is what you say after you punch and/or kick a guy in the balls. This is a good revenge to use on douchebags. Here's what you do:

Knock on douchebag's door.

When douchebag answers, come at him like a spider monkey- a deranged, rabid spider monkey.

Punch/kick him right in the nuts.

As he writhes on the floor and cries, "Whhhhyyyy??!?!?!", You point at him and yell very scarily, "YOU KNOW WHY!!"

And he will know why.

Revenge accomplished!

How to correctly carry out a "you know why."

Dave (answers door): Oh, hi..
(Sara, crazy eyes and all, punches Dave in the nutsack)
Dave (falling to the floor): WWWWWHYY?
Sara: YOU KNOW WHY!
