The london trick beef? a.k.a 5th Floor Fixie Crew Implosion

I don't think the other 'explanations' of fixed trick riding are altogether fair. I think that apart from it being fun (shock, horror), the appeal lies in the fact that it's a kind of acrobatics on bikes. Not everyone is naturally into 'traditional' applications of cycling, e.g. long-distance riding or road racing. Some people are naturally more interested in performing acrobatically. It broadens out the appeal of cycling.

Sorry, I didn't phrase it properly. I wasn't really asking what they were doing, I was wondering why what they were doing was so unbelievably shit.

Maybe I'm coming at this from the wrong angle, but I find street BMX to be really engaging. It makes fixed trick riding look like poop.
