A Bit Like Trainspotting But From *Behind*

I received a bulletin broadcast on MySpace today (being rather new to MySpace myself) about this and was rather amused. It's probably less sad than trainspotting but not much.

You probably don't know what I'm going on about so I might as well put you out of your misery and tell you that I'm talking about train-mooning.

Yes, people get together, drop their trousers and show their arses to passengers on board trains. Why they are motivated to do this I don't know.

It's even got a dedicated website (perhaps one of many) - see here.

If you're curious as to what it looks like:

I don't think I'll find myself at one of these events, not unless I'm very drunk.

Apparently showing your arse is ok but frontal nudity is fronwed upon. I don't suppose it'll be called "mooning" then, would it?
