OMG, I'm Greek the word sounded awfully lot ancient Greek to me and I heard it a couple of times, even misattributed to Ancient Greek scholars etc. It is a portmanteau of "πέτρα (petra)" meaning "rock" and "ιχώρ (ichor)" which is the mythological golden substance in the blood of the Ancient Greek Gods. So this sounds all pretty Greek to me with all the quirky mythological stuff that come with the Ancient Greek but here the thing. The first time people (some Australians) came up with the work was in a 60s issue of Nature http://dx.doi.org/10.1038/201993a0 http://dx.doi.org/10.1038/201993a0 Looking forward to tease my acquaintances that claim "our ancestors had such a diverse dictionary they even had a word for the pleasant smell of rain".
