Petrologic 

Petrologic. Its Petros' actual world, a lot different than the ordinary one; It is multidimensional, electronic music plays in the background; a non-judgmental place with lots of nice people! Drugs don't exist there as Petrologic is a drug itself! Not everyone can understand or experience it as its structured in such sophisticated Petrologic way that makes it nearly impossible for non cool people to decode it.. In order to gain access to Petrologic you have to pass a certain assessment by Petros himself and be on the same frequency.

Oh my god! Last night me, Tina and Petros were totally Petrologic!
Those guys have gone bonkers.. I think they will get Petrologic soon..
