Puma Style was originally developed at East Carolina University in Greenville, NC. The phrase was coined to clear up confusion to if Doggy Style was referring to anal or vaginal intercourse. Puma Style is a term to describe the act of vaginal intercourse from behind. This action was originally seen in the wild, where the endangered black puma mated with its partner to assert its dominance.
