ridonkulously 

(adv.) ri·donku·lous·ly (see ridonkulous).

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.

Ridonkulously is the adverb form of ridonkulous.
