Military grade marijuana developed by the U.S. government in the early 1990s. It was believed by military intelligence that the mellowing effects of this particular strand was so potent, that introducing it into the Somalian drug supply would effectively cause the guerrilla fighters to lose their motivation to fight. Unfortunately this proved ineffective, because smoking it gave the guerrillas such a powerful case of the munchies that they began raiding nearby towns to obtain snacks, violently stealing millions of dollars worth of U.N. food relief. The events of this particular conflict were chronicled in the film "Black Hawk Down."

In recent years Black Umbrella has become available on the U.S. drug market, although due to its reputation of potency it's usually avoided by anyone other than experienced stoners and dumb rich teenagers who don't know better.

Miley: "Just give me that blunt and I'll last all night! I wish I had like, 500!"
