Any idea on what kind of consensus mechanism PoG is?

I came across a post on Bitcointalk where a guy talks about some airdrop for hardpog coin, but no further details. A google search doesn't yield anything much at all on what hardpog is.

I'm guessing the pog of hardpog refers to a consensus mechanism.

So far, I have found a few consensus mechanisms that use the acronym PoG, such as Proof of Growth, and Proof of Gaming, but nothing else.

Anyone have any idea on what other consensus pog could be referring to?

Better yet, any idea on what project hardpog could be?
