Joe, Kat - my greetings!
Thanx for care and answers.
I know what is chain.
The question is what mean " YANKIN' " ?
(for example I got the sentence from that song "yankin' my chain")
I am asking 'cause in my dictionary there is no word "yanking".
May you can tell me other meaning of that verb?

Kat, outstanding job! Absolutely correct!
