Today is Good Friday. I probably shouldn't introduce a rude phrase. But, what the hell, learning knows no bounds. By the way, I am not a Christian nor am I a Buddhist; though I do believe in Buddhism.
Anyway, back to the subject. While I was watching a movie, I came across this slang "talk to the hand". It is used to say in a rude way to tell someone that you do not wish to listen to what they have to say and that they may as well stop.
