Rumored to be OG Kush x F1(undisclosed strain by original breeders) x Durban Poison.
Very little is known about the origin of Girl Scout Cookies. The only certainty is it was bred in San Francisco, California, sometime in the last couple of years; perhaps 2011 or 2012.
The strain was developed by a Nor-Cal group of associates known simply as the Cookie Family. From there, different phenotypes (some perhaps bag-seeds) have been distributed throughout the United States. Most notable of this array of Girl Scout Cookies is the "Forum Cut," made available through internet networking among breeders.
