New years eve

So I've got a party organised it's going to be 5- 6 of my guy friends ( I didn't want this many but they basically invited themselves) and 1 Russian chick I met the other day and her guy friend who's not her boyfriend and 4 - 5 more of her friends I really hope she brings some girls other wise this is going to be a cockfest. I reckon I can full close the Russian chick but this could all back fire because she isn't 100% sure if her and her friends are coming or not so if they don't show up I'm going to be mega pissed off because then it will be 6 guy cockfest and I'll have to head down to the foreshore and try and pick up like I did last year. I guess we will see what happens.
