What? If the same rare term gets used in two forums for the same game a couple days apart, it is hardly far fetched to think they may have been made by the same person.
I made no judgment at all on your comment. I've never even seen a Zero Punctuation video, and hadn't heard of it until you mentioned it (the similar Steam forum post mentioning Yahtzee didn't mention that, that I recall), though I got the general meaning from the context.
