Okay, that long word is way too long.
floccinaucinihilipilification however, is a fine word, one that I have often used.
For example, when you are mad at someone, but don\'t want them to really insult them, just confuse them, you can say:
\"Karyuu, why do you always have to be such a floccinaucinihilipilificatrix?\"

(I\'m not mad at Karyuu

)
P.S. That\'s why Robert Heinlein is the best author _ever_. That\'s where I first came across this word, in one of his novels.
