ugh...20 bucks says this guy threatening you is full of bullsh1t. Cmon now, when you think of asian gangster, you imagine guy in black suit, smoking at a wood table surrounded by 20 other black-suited gangsters, also smoking. You DON'T think of horny chinese geek picking up women on the internet.
Cmon now, if the guy had "so many buddies" and was "so tough" i think he would have come to your house "with all those buddies" and smashed a few windows or something. And can you really imagine what he would tell his fellow asian gangsters?
"uhh well ok guys i was picking up on this chick online and she turned out to be a guy...."
personally, i have no respect for asian gangs, because they have a very obvious lack of balls. And i'm asian, i can say that. They think they're soooo touch, but refuse to fight when the odds are even CLOSE to being fair. Unless its 1000 to 1, theyre not going to get involved.
i think you should step outside when he comes out and tell someone to get your back in case "his buddies" jump in. Then proceed to introduce his face to Mr. Curb.
