Skoden

A native American folk hero of Chuck Norris-like status. There is abundant tall tales of his legendary strength, resilience, and proactive attitude. He turns up where he's needed without warning and after he's finished he disappears just as rapidly. He's also a Boogeyman of sorts that reminds people to watch their mouths when addressing their elders or when they don't know what they're up against.

Sko•den = let's go then.

I wouldn't call it a battle cry, but it's often the last intelligible words shouted to an opponent before violence ensues.
It's also used to signal to the group that it's time to leave.
The urgency of the call is directly affected by emotion. Use your best judgement. when you hear it you should already know if you should take your time, prepare to defend yourself, or run for your life.

What? No I didn't see who knocked you out when you were talking smack. Some dude just shouted "SKODEN!". Then put you down. I've never seen anybody get knocked out that fast. You were being an asshole so nobody really tried to stop him and he wandered off after he made sure you were still breathing.

"We're out of tobacco AND beer??? If it was just the smoke I would have waited. But it's Sunday tomorrow and the liquor store closes in half an hour!"

"Really?? SKODEN!! Tha fucks takin you so long?!"
