Not like any human being would honestly, actually use this word, but that's exactly the point: it's a gnomish word, embodying gnomish values, and only a gnome or gnome apologist would even use this word.
floc·cin·au·ci·nih·il·i·pil·if·i·ca·tion
(noun) : the estimation of a thing as worthless
(verb) : the act of rendering something as worthless or inconsequential
I want to buy a new car, but I am not looking forward to the floccinaucinihilipilification of my truck when I try to trade it in.
*shaking head*
Anybody even using this word in conversation rates a cockpunch.
