'I went to urbandictionary.com by accident because i typed in 'egads' in the search engine. I thought nobody came up with the word 'ridick' yet so i added it and sent it to the editors. When i clicked on the link, it turns out some jackass named Spina already made up that word in May of 2005. Now that's ridonkulous!!!
