that's an interesting point RD - who tracks the first use of a word - surely waiting for something to get into a dictionary isn't a valid argument as to first use as colloquial expressions and words might never get into a dictionary, also fashionable phrases come and go very quickly, others are part of local dialects and never get into a dictionary.
regards chrome - the bad faith test comes when the domain is put to use, not in the actual registration unless its a TM - as far as I'm aware... so maybe the guy doesn't wanna sell chrome metal, it could be used for any number of things and still not be considered bad faith unless he tries to profit from the google browser in some way. just regging it on its own is not enough to cause a panel to see bad faith is it - you have to wait and see what happens on the domain.
my favourite story about this is BAA.com which was originally regged by some guy selling sheep or something and the British Airports Authority tries to get it off him claiming bad faith or something, but the panel said the use was legit.
