Introducing Whorechalking...
First there was war-dialing - where brute force was used to ring hundreds upon hundreds of phone numbers in the hope that one of them would give you access to a computer network. Then came war-driving - where geeks drove around with wifi enabled laptops looking for unsecured wireless networks. And then came Warchalking, where people could mark up in a symbolic language what wireless networks they had find. And by way of a natural process of development, we come to the zenith of all such enterprises - cutting the very heart of the human condition - catering for the most basic of base needs.
