You know what you doing 

"You know what you doing" first appeared in a game for the Sega Genesis called "Zero Wing", along with the phrases All your base are belong to us and You have no chance to survive, make your time.

One uses this phrase to point out that the listener is or the listeners are capable of finishing some task.

Alexander: I'm going to call the guy, and convince him that we are right about this.
9001: You know what you doing!
Alexander: Thanks for the encouragement.

You Know What I'm Sayin' 

A phrase used by people, usually from inner city ghettos and poor, non-English speaking backgrounds who want you to constantly know what they are saying when in all reality, they aren't saying a God damned thing at all and basically are just wasting time from their boring, low life lives at home with the baby's momma watching Dora the Explorer with all 5 of their kids who in fact have 5 different baby daddies.

A pathetic and inexcusable phrase or form of continuing one's thought inside of a paragraph being spoken that really makes no sense at all but to literally give everyone listening a splitting fucking headache!

Another form of this phrase is most commonly: "You know what I mean?"

Person: "Like, dude, you know what I'm sayin'? And then all this other stuff happened, you know what I'm sayin'? So since then, you know what I'm sayin', I just decided to go home.

Me: "No dude, actually, I have no idea what you just said."

you know what i mean? 

something a girl will say in the middle of sentences with a little squint and head cock to register that you agree with her, but without waiting to see if you actually do (know what she means, or agree) before continuing on with what she was talking about.

Can be abbreviated to "you know" if she is in a hurry to get to a lot of important information.

further abbreviation while texting is commonly seen as "u no?" this version eliminates entirely the need or possibility for instant approval (real or imagined), requiring the textee to actually respond, or risk insulting her by not automatically taking her side.

She: "So I was talking to my friend today about how my dogs were barking at the neighbors when they walked around their backyard and how they like, were just barking, you know what I mean, and the neighbors were like, could you please tell you dogs to stop barking, and i was like, really? you know what i mean? like, they're asking me to keep my dogs quiet while they walk by my house? Really, that's so rude. You know what i mean?"
I: O_O
