Intentional mispronunciation of "ridiculous" (based on the common misspelling) to indicate that something is ridiculous while also insinuating that somebody involved is stupid (i.e. implying that they are just as stupid as people who misspell "ridiculous").
Example: Person1: John says Bruce Willis is in Star Wars
Person2: That is REDiculous (i.e. John's idea is ridiculous and John is also an idiot).
it is like ridiculous, but it is someone who is consistently ridiculous and over exaggerates things to ridiculous measures, when someone is constantly calling someone ridiculous you start to annunciate the "ri" turning it into a "re" thus making rediculous.
rediculous - n. (ree-dik-yew-lus) the act of licking ones dick again. From the root word diculous and the Latin prefix re- meaning to do again.
Example: NoScoper360: "Man I can't believe we lost that game, this shit is rediculous."
SmartAss69: "ri*" 360: "ri what?"
69: " ridiculous, the correct spelling is ri-diculous"
360: "NO, re-diculous is just diculous again. Like liking someones dick again, that how bull shit this game is."
