A word that means nothing, just meant to confuse, something you say to deflect someone long enough in conversation so you can get the fuck out of there. Usually most effective in the form of a question.
"Yes my little kitty cat has the cutest widdle face you ever seen."
"Um, curchip?" (backing away)
"? I, uh, don't... What is that word?"
"Crap, that's my ride, later."
