It's 6:45 pm on a drizzly Wednesday evening at Waterloo Station. The main concourse is crowded more than usual due to train delays. Anxious faces stare at blue screens hoping for their cue to sprint to a platform in the hope of a seat.

The middle aged lady with handbag in one hand and mobile phone in the other looks down for a second and stares in bemusement at two young ladies who begin dancing to the sound of their personal stereos.

She shakes herself to check her senses are not playing tricks as a Conga line streams past behind her with 20 or 30 people listening to their own personal stereos. Other commuters look on dumbfounded.

Welcome to the world of Mobile Clubbing. Simply, mobile clubbing is turning up at a pre-arranged public place on mass where you begin to dance to the sound of your own personal stereo. It is unclear where the concept of Mobile Clubbing originates but one thing is clear and that in the world of spontaneous mass public gatherings, it has replaced Flash Mobbing.

Throughout the UK, events are organised on the Internet, informally among groups of friends and the word passes via chat rooms and news forums.

But what is the point of meeting on mass and dancing to the sound of your own personal stereo?
