I've played a troll before, but the female troll actually says "For Vol'jin" when /charge. I'll double check my hearing on the -something-'jin word.

Edit: Tested both male and female out on charges. The female troll didn't sound clear enough so I don't know if she said Vol'jin or Zul'jin. Male on the other hand says Zul'jin.
"For Zul'jin, wait, we're killing him QQ"
