A Googlewhack a search term containing a combination of two or more words that will produce only one single search result in the Google search engine. This means finding only one single webpage on the entire World Wide Web that contains your search query. Googlewhacking is the name given to finding such a search result, and is considered to be a "Web sport".
The rules to Googlewhacking are simple:
1. You cannot use quotation marks in your search query,
2. The words must be found listed in dictionary.com,
3. The page must be an actual article or webpage with information not just a list of words.
One problem facing Googlewhackers, is that when a googlewhack is found and reported on the web, this means your query will no longer count as a googlewhack since the page it was reported on will most likely be indexed by Google, thus creating more than one search result for your Googlewhack.
