When something is so totally unreal or absolutely preposterous, that the word ridiculous does not come to close to explaining it.
Any of the above definitions that claim to have started the word ridonculous in the past 10 years, are in fact ridonculous. The word ridonculous has been around for at least 20 years as I have known it all my life.
