I like the video... It is fun, and pro-bitcoin.
I also did not know what the fuck or who Zhou Tonged is, but it appears that from the urban dictionary,
"getting zhou tonged" has gained some notoriety, like the way we say "getting roached" in this thread.
Anyhow getting zhou tonged is getting margin called.
You didn't get Zhou Tonged?
Noob, I lost 10 BTC to the guy.
And no, it is not getting margin called. Zhou Tong was the proprietor of Bitcoinica, the very first (that I know of) platform where leverage was available, it is true, but the term refers to the exit scam he pulled.
I never used the leverage option there. I still got Zhou Tonged.
