Dirt is an exact replica of "dirt".
My girlfriend is allergic to pollen and humid dirty places, she gets asthma. Well, when I got my bottle of DIRT I made it my scent of the day, while I was driving with my GF she got sick, she told me there was something in the air that it was making her very sick, she told me to pull over. She got out of the car and tried to calm down, it was only then when she told me it was me smelling dirty, rancid, humid, dusty and disgusting.
Believe it or not DIRT was so very much dirty that triggered a psychosomatic reaction on my GF. The driest scent I have ever encountered and my best friend when I want to play games with people, I spray their jackets before we go out, in the car, etc ... it is simply unbearable !
