A greebo is a person who does not "fit" into the crowd. Thus they (by default) become a greebo, however they can never admit this. Also the person may of had something happen to them, and therefore feel the world owes them. I do not hate greebos, a a lot of friends are greebos, and no i am not a townie/chav/pikey, although a lot of my fiends are them to. The concept sucks to, become a greebo to be "different", but you all look a like, and there are so many of you. Though you will claim there are more townies, but that is because you class anyone who is not one of you a townie other then business men/woman. So people who dont class themselves as anything are townies to you.
Some greebos are cool

But most need to get over themselves and realise not everyone has a grudge against them!
