Googlebomb is an attempt to influence the ranking of a given site in results returned by Google. Due to the way that Google's search algorithm works, a website will be ranked higher if the sites that link to a page all use consistent text. For example if you register lots of domainss and all of them link to the main site with the text "... is a living legend" then searching for "living legend" on Google will return the main site high in the ranking.
A common means of exploiting this is through weblogs, where although the entry may disappear from the main page quickly, the short-term effects of a link can dramatically affect the ranking of a given site.
Most recent and popular examples are, amongst others, miserable failure (or just plain failure), weapons of mass destruction and french military victories. Best results are obtained when using the "I'm feeling lucky" button.
