An adjective to describe something that is worthy enough to be called exceedingly preposterous 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!
What you say when you you are stunned by something that makes you feel incredulous. It's like ridiculous wouldn't pinpoint the foolishness, but ricockulous hits it. Ricockulous. This word is usually used after the word fuck. Use it.
I mean you should've seen this f***ing tv, it was f***ing ricockulous.
