What is the coolest word?

poop chute!

Message passed on from Mary Poppins:

Supercalifragilisticexpialidocious,
Even though the sound of it is something quite atrocious,
If you say it loud enough you'll always seem precocious -
Supercalifragilisticexpialidocious

my coolest words are "eurepean union" and "judgment".
I feel the first one is smooth and the second is funny

Sometimes I wonder where English has picked up some of its "-ious" words. The coolest ones for me: preposterous, audacious, supercilious. Feels like they must have popped out of the head of a mediaeval university scholar. :-)

There are too many words to like; the madness won't stop! Evidently after reading Damian's and Easterner's posts, I've just realised that I like the -ous words too, the ones that have sound endings like 'atro-cious' and 'preposte-rous' rather than 'supercilious' or 'superstitious'.
