*accidonkulously (adverb): accidentally + ridonkulously = a word used to describe the action involved in an accidental but particularly kooky, bizarre or freakishly embarrassing mishap: Upon entering the parking space, I failed to notice the shopping cart and accidonkulously rammed it into the RCMP officer's car. See Tiger Woods for plenty of other examples.
* "Accidonkulously" sounds better than "accidiculously" for uh, obvious reasons. BTW, the etymology of the word ridonkulous (as a replacement for ridiculous) is apparently as follows: "created in the backwoods of a Mississippian moonshiner in 1968." The story goes that he was so drunk on moonshine that when he tried to mount his donkey (named Jimmy), it kicked him in the face and he was nearly killed. After regaining consciousness, he described the whole experience as "ridonkulous!"
