Hey Ladiesdrink, first of all, welcome here!
To the discussion:
Yes, this is definitely a technique and therefore I really have my doubts about it. Actually, I don't see much difference between adopting a certain facial expression with Cory, and adopting a certain "confident" body language like all the PUA posers advise.
In my opinion, its exactly that kind of stuff that keeps guys away from learning the real deal. And I know that Cory Skyy teaches the real deal, too. But guys see Cory Skyy and they are used to thinking that getting girls needs techniques and don't have clue about that THEY have to change and not their behaviour. So they come to Cory and see "oh, an eye game techniqe, I need that" because they search for techniques and nothing else.
As I still was in the PickUpCommunity (2 years ago) I did think exactly this way. I listened to a Brent podcast back then by accident and all I took from it was things that I thought I can use as a technique. I was ignorant to the real stuff, no wonder since this whole freakin' community is ignorant to it!
And anyway, if using fake facial and body expressions would work, then the PUAs wouldn't be such creepy guys without success...
No offense man, just my opinion about it
