A term given to the mispronouncation of a word or the jumbling of a sentence, which renders the speaker's statement completely and utterly useless (but hilarious!)
The speaker is generally aware of what is happening, but is unable to prevent the pardy-karr-karr from unfolding.
'Just going to my birthday's brother.' 'Did.. did you just pardy-karr-karr?'
'Can you pass the buhjkmbftuyhbjkbhvgtffutiyugoihjkn. Damnit! Pardy-karr-karr'
