Origins: Originally made to counteract the word H.A.M.( Ham) because of its lameness and also because bacon ( the actual food) is way better than ham ( the actual food).
The backwards way to spell the phonetic alphabet is not the way it is listed originally. They have interjected an additional ghi into the correct way of spelling it which is
z y x w v u t s r q p o n m l k j i h g f e d c b a
And not
z y x w c u t s r q p o n m l k j i h g f e d c b a
