He had to be.
I don't think he was aware. The way the dude is holding it, like he's cupping it. It looks like a little 'sleight of hand"
to me.
Though I read an interview once where it came up and Kai had a reasonable attitude about it. He more or less said he knows he gets a lot of shit for it online. His attitude was like he understands people are going to laugh about it but he did what he did and it is what it is. He did it at a time he needed to make money.
I thought that was a decent take for him but I did not get the impression that he would have a good enough sense of humor about it to laugh off some fat Asian kid making a fool out of him straight to his face.
