Fear of rocks. Commonly triggered by Minecraft builds, which use cheap blocks like stone, cobblestone, etc. (anything stone related/grey). The grey hue of rocks makes buildings look dull, unattractive, depressing, cheap and lazy. Usually the viewer suffers from this disorder, not the builder themselves. The stone dominant builds are common in survival medieval builds.

Alternative spelling: Petraphobia/Pietraphobia
"I can't believe in this day and age, people still think that cobblestone is the only building material there is" -"Dude, why do you have to be so petrophobic?"

Patient:"I don't know what's wrong doc. Whenever I see my kids play Minecraft I get sad"
Doctor: "Ok, I will schedule you for a petrophobia test"
