Normally a sexual predator who is infatuated with their own feces. Using the crap-freezing technique, they target young Asian girls, scarring them for the rest of their lives. They tend to have dark shaggy hair, a funny accent, and live near busy areas such as Ex. Orlando. They have specific target days. The most common Tuesday, and to them its referred to as (cheeseday). We can only guess why?
Pooki: Don't go walking around by your self on tuesday!
Wendy: Why?
Pooki: The pooperator will come for you*scared face*
