Origins: the adjective root, ridonkulous, evolved from the ithyphallic wordplay of replacing the "dic{k}" sound in ri·dic·u·lous with "dong" (the "g" becoming silent). The spelling of the root using a "k" instead of a "c" results from the common misconception that the word donkey is somehow related.
An adjective to describe something that is worthy enough to be called exceedinglypreposterous that is deserves an even more absurd name than ridiculous.
Person 1: Oh my god! Did you hear that Ashley Olson is dating Lance Armstrong?
Person 2: That is absolutely ridonkulous he's almost twice her age!
Having the qualities of being ridiculous, but to a greater, perhaps exponential, degree. Marked by crazy ass qualities that make you laugh sooooo hard. Fucking hilarious.
Johnny Cash relapsing into drug use because his pet ostrich kicked him severely (boot party) in the 1980s (AD!!!). So an ostrich makes him shoot up?! Ridonkulous.
