Thrift Shop and Game

The amusing and popular song by Macklemore is a veritable primer of Game.  It begins with irrational confidence: "Walk up to the club like, 'What up, I got a big cock!'"  Key word: like.  Whether he does or not is irrelevant, it's the being pumped up that allows him to successfully imitate the alphas, to such an extent that even the brothers who would normally disdain their Caucasian competition are forced to acknowledge him as their superior in style: "Damn! That's a cold ass honkey."

The language throughout is masculine.  The Thrift Shopper is not self-pitying, he's not lamenting his lack of money, indeed, he is triumphant over even the smallest victories, the most insignificant come-ups. Contrast with this the sad, pathetic figure of the gamma who has a good job, a house, and a nice car and still feels the deck stacked against him.  He's not shopping, he's "digging, he's "hunting", he is a literal man of action.

The peacocking aspect should be sufficiently obvious as to require no explication.

The Thrift Shopper is centered on himself and confident that others envy him.  He doesn't compare himself to those around him, but to the iconic John Wayne, and not to his own disadvantage either. It's not the clothes that make him cool, he is what makes the clothes cool.

I could take some Pro Wings, make them cool, sell those
The sneaker heads be like "Aw, he got the Velcros"

He even AMOGs the more fortunate who are foolish enough to spend $50 on a Gucci t-shirt and expect to derive some advantage from that.  He knows that distinguishing himself from the crowd is more important than having the right, most fashionable stuff.  And while those lower on the socio-sexual hierarchy will complain that he is a clown and has no rational basis for his superior attitude, the women will not care, but will flock to him.

And it inadvertently reveals the secret of what women actually mean when they advise: "Be Yourself" in order to attract women.  They're not lying, they are simply not being sufficiently clear due to their inability to fully understand what it is that appeals to them. What actually attracts them is not a man being himself, but rather believing in himself.

What the specific belief happens to be is almost irrelevant.
