I'm not judging. I'm just curious about anomalous or not-fully-developed forms. And listening to sports broadcasters nee athletes is a good way to find odd constructions. Just before overtime in game 2 of the NHL western conference final Brian Engblom recapped the events of the game so far, explaining that at one point a fan "threw an octupi on the ice."
I've mentioned the plural of -us words before. In that post I said
Octopus comes from Greek so the plural would be either octopuses or octopodes. Octopi has wriggled its way into common usage and its tentacles are holding firm.
But I was only thinking about the plural form when I wrote that. I had no idea the reach had extended even onto the singular.
