What did is said after that in the same posting?
So yes. You are taking what I said out of context.
It is colloquial. OVER AND OUT. I AM DONE WITH YOU. DON'T WANT TO HEAR FROM YOU AGAIN.
Yea, of course you are done. This is like offering to resign after you have been fired, or calling for a draw after you have been checkmated.
"Quote me if you dare" - that was classic.
