Arsebook.

I swear, if Facebook gets any more addictive, we'll have rich kids snorting lines of (Super)Poke from the arsecracks of hookers, psychologists will study the urge to draw imaginary rectangles around people and 'tag' them, people will start popping $1 virtual gifts instead of Ecstasy, sheep and cows will be defenestrated by zombie ninjas, and possession of over 2kgs of "new notifications", or 500g of "please confirm friend details" will be punishable by death in Malaysia.
