No idea what you're talking about, I'm afraid; it's a reshuffling of the marks awarded in the "rock dodging" scene (they didn't have any ice handy, you see) that featured in an episode of Avatar: The Last Airbender. Korra's implication that there are others available is my own addition to the mythology; we only see these same three in the ATLA episode, but nobody ever actually says those are the only possibilities.

Not quite:

First seen back in Clarion Call, at the first attempt at Corwin and Utena's wedding, and again in Try, Try Again.

It's actually the reference icon in the Asgardian technical diagram standard for denoting "power output here", but don't tell Utena.
