It seems like fairly general purpose mockery, actually.
I blame that Austraillianasian guy, Hong. He's not a real Austrianesianalian; he doesn't seem at all like a crocodile-hunting, Foster's-drinking, eating-at-Outback-Steakhouse kind of guy! He hasn't even got a real accent. Never says "mate" or "shrimp on the barbie" or anything.
Wait. He's the same guy as Piratecat. So it's all Piratecat's fault!
For a moment, I thought it might be my fault. But I'm really Eric Noah, so it can't be my fault.
[Edit: misspelled "Austran"! How embrssing.]
