Off topic:

Someone pmed me to ask me to post what "talk to the hand" means. Here's my explanation:

"Talk to the hand" is a contemporary Black colloquial saying ["contemporary" meaning at least from the early 1990s. However, I'm not sure when teens and young adults first started saying this. I don't recall hearing it said before the 1990s]

A longer form of this saying is "Talk to the hand cause the face don't give a damn." What is actually meant is "Talk to my hand cause my face [my body, my mind, my soul] don't give a damn about you, let alone about what you're sayin".

When a person says the first part of that sentence-"Talk to the hand"-the second part "cause my face don't give a damn"-is implied, and understood by the person addressed and other persons hearing that statement.

"Talk to the hand" etc. means that you don't want to even waste any energy acknowledging the existence-let alone the words of the person-you are addressing. "Talk to the hand" is generally considered something that females say, though I'm sure males {particularly pre-adolescent males} probably say it too.

"Talk to the hand" is something a female says to another female who is trying to get her riled up {angry}. Keeping one's cool under fire is an important part of African American culture. In that culture, when you react to a person with emotion and particularly with anger, you're admitting that that person has gotten "next to you". When a person "gets next to you" {"bothers you emotionally}, you've lost the battle.*

"Talk to then hand" is said in a stern, no nonsence voice with either a "grittin" face {a harsh, snarling face}-hand gesture #1 or an expressionless face-hand gesture #2.

Either one of these two body gestures are made when a person says "talk to the hand"

Hand gesture #1. The person saying "Talk to the hand" purposely violates the personal space of the person she is addressing by moving very close to that person and putting her hand palm up {in a stop position} very close to that person's face. Violating that person's space is part of the purposeful insult that is given when you say "talk to the hand". Btw, "getting in somebody's face" in a confrontative manner-with or without the "talk to the hand" gesture-has become a street saying in and of itself.

Hand gesture #2. The person saying "Talk to the hand" stands straight with her head averted to the left {in a direction away from the person who has offended her or him}. The person who is saying this holds her hand palm up in a stop position very near the level or her own or his own neck level. This "Talk to the hand" gesture is the same as or very much like the "Don't even go there" gesture.

That gesture means -Stop what you're saying because I don't even wanna hear it".

After a person says "Talk to the hand" to somebody, that person no longer engages in conversation with the person she addressed. If the person addressed responds with some putdown saying, the first person ignores her and refuses to re-engage with her.

The Urban Dictionary
has three definitions of "talk to the hand" and a visual of the "in your face" hand gesture {hand gesture #1}. Each of these definitions are okay but prefer mine :o)

* This coolness under fire is the emotional state of being that persons are supposed to have and to maintain when they are playing The Dozens. When playing the dozens {exchanging witty putdowns}, the person who loses his or her cool, and reacts {responds} with angers, loses.

And that is what I meant when I said "Talk to the hand" to the person who shall remain nameless.
