Retardiculous 

Something that is so retardedly ridiculous it's retardiculous...

I once was about to blurt out the "R" word in front of someone who has a disability. I tried to say ridiculous instead but it was too late...I had already begun to say "Retard...so out came RETARDICULOUS"

used when something is mind blowingly stupid, shocking or awesome...

Used in a sentence; "holy fuck! that is retardiculous!"
