Say whaaaat??

The book I'm reading at the moment is full of big words. Gi-normous words. To the point where I read it holding the book in my left hand and the dictionary in my right hand. So it was with some amusement that I came across this rather large lexeme the other day...
Polyphloisboiotatotic.

Huh???

According to the Oxford English Dictionary this ridiculously huge expression translates to:

'That roars most loudly of all or very loudly indeed'.

It was once used (probably the only time it was ever used in the history of etymology) in a sentence by William Makepeace Thackeray, when, in 1843 he wrote:

'The line of the shore washed by the poluphlosboiotic, nay, the poluphlosboiotatotic sea.'

Respect.
