Her companion just kept nodding, but it was pretty clear that not only did he not know what she was saying, but he wasn't even really listening. I think the problem with this communication was that, in my experience, most people who interject much of what they say with, "You know what I'm saying" are engaged in that major league jibba jabba my good friend Mr. T doesn't have time for.
"You now what I'm saying" is interchangeable with:
You know what I mean?
All I'm saying is...
Am I right?
Ya know?
The jibba jabba response to such useless questions is often:
I hear what you're saying.
Yeah, I know.
What your saying is...
So, you're telling me...
You're right, you're absolutely right.
Get out of here.
You basically can carry on an entire conversation of "you know what I'm saying" without ever saying anything. For example:
Idiot #1: All I'm saying is that he doesn't know what he was talking about. You know what I'm saying?
Idiot #2: So you are saying that he doesn't know what he was talking about? I hear that!
Idiot #1: Exactly, that's what I'm saying. Like I said, he doesn't know what he was talking about, ya know?
Idiot #2: I know what you are saying. You are absolutely right. He doesn't know what he is talking about. Ya know?
Idiot #1: Yeah, he doesn't know what he is talking about. That's what I said.
Idiot #2: What?
See what I'm saying? So I have prepared some conversation stoppers for people who use the annoying phrase and other annoying verbal ticks like, "You know what I'm saying?":
No, I don't have a clue what you are talking about.
I hear what your saying but it sounds just like, blah, blah, blah.
Did you say something?
Do you speak English?
Stop saying "You know what I'm saying" or I'll dope slap you from here to the next corner.
Enough said?
