BMFC Parties

Has anyone been to a BMFC party before?
What was it like? What kind of guys went to it? Was it mainly thug style guys?
How well vetted are the guys?

Lots of questions and probably only for the UK lot.

I'm really curious what kind of guys go there. Do they strut about like they know they're going to get some 'action' so they don't put much effort into it?
