This person suffers from a term they coined PTSD: Planking Traumatic Stress Disorder. We would, too. If you accidentally stumbled upon hundreds of people planking, what would you do? Join them? We’d run the other way. These kinds of strange, one-off real-life scares are something we like to avoid. At least the world wasn’t ending, and there was a simple explanation for the absurd amount of plankers (via Thequeensarmpit).
