Talk to the hand (?)

What does this construction mean?
I can not figure it out, it seems to have a new meaning every time I hear it.

I guess it means whatever the movie script writer wants it to mean.

It's a slang pop-culture expression. It started out as a humorous expression among African-Americans, but then it got mainstream.

"Talk to the hand sista, cuz the ear ain't listenin'."

It basically means: "I'm not listening to your nonsense."

Oh....the expression says "talk to the hand" because it usually involves putting one's hand in the other person's face as if to say "I'm not listening to you."

BTW, folks....I don't use this expression as I think it's silly....just explaining it.

So there you go. mjd's answer seems better than mine. I've only ever heard it once (you guessed it: in some movie or other). I've learnt something. What a silly expression. I'm not about to include that one in my reportois.

to anyone who is considering adding this cring-inducing expression into their repertoire,

Please don't. It's a relic from the mid-to-late '90s where it rightfully belongs (along with other embarrassing pop culture expressions like, "WHAAAZZUP???")

The movie you are talking about is "Terminator the III".

Yeah, that's the one ... mid-to-late 90's ... T3's got such an early-to-mid 80's feel about it.
