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.

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.

Do you know my dad? 

A vague question one asks angry, deep-voiced British skiers after being told not to give someone the stick. Usually answered by a baritone note.

Snowjob: "DON'T GIVE HIM THE STICK!"

Kid #1: "We're sorry-"

Kid #2: "Do you know my dad?"

Snowjob: "WOOOOOOOOOOOAAAAAAHHHH!!!!!"
