How can you skid / How to do skids / skidding

I'd avoid the rear skipping jumpy method mentioned above as imho it looks like you need to take a shit when viewed from behind and anyone who doesn't know what you are up to will think you are peculiar.

That's absolutely retarded. Do people really give a shit what they look like when they are controlling the speed of a bike?

I just got run over by a lorry and killed, but don't worry - at least I didn't look like a geek by doing something to avoid the collision.
