Pronounced ra-dick-you-lus. Considerable force is used when saying this word, but it is not to be shouted. Something of absolute incomprehendible absurdity. Usually associated with positive connotations, but can also be used negatively. It's origins are believed to be a joining of ridiculous and radical.
