What is the coolest word in the English language?

How to pick just one?!?

But I offer: crepitations.

Added word: I really can't settle for one, but I will stop at two. Second offering:

pneumonoultramicroscopic

silicovolcanoconiosis

That is all one word, but Answers somehow wouldn't let it be on one line.

" insegrievious " it's an adjective coined by Gary Owens, a Los Angeles radio and TV personality whom you may have seen on the most recent Emmy Awards program.

He was the announcer from Laugh-In with the great deep voice.

The "coolest" thing about this word is that it can mean whatever you want it to mean and it's cool sounding too !

Phoenix

I like "chutzpa." It's a Yiddish word, sometimes described as the attitude you have when you first crap on your neighbour's doorstep, then ring the doorbell and ask for toilet paper. The spelling varies a bit. By the way, I think you meant "e.g." rather than "i.e."

Love

Ecstatic

Coolest word:

Fitzgerald.

Not exactly a word, but still something that sounds cool.

I just love the word 'chic'--the way it sounds and the meaning. I also like conundrum. And flabbergasted! Riboflavin! Cynicism! lol yeah i'm weird

Ice frigid Kelvin

One of the longest is antidisestablishmentarianism.

I just read the other answers and I see some one else came up with antidisestablishmentarianism. That's amazing.
