if you have been lolbanned, you have been saying LOL (shudder) too much, whether via PM or text, or even...OUT LOUD!!!
yes, its true. if anyone is to be heard SAYING "lol" they must be immediatly be beaten with the nearest heavy object whilst you should 'LOLBAN!'
geek: 'look at that guy on his bike. lol'
you: 'LOLBAN! you've just been LOLBANNED!'
