AFAIK there is no such document. The only sourcing for the slang terms was an anonymous 4chan post.
“hotdog” = boy
“pizza” = girl
“cheese” = little girl
“pasta” = little boy
“ice cream” = male prostitute
“walnut” = person of colour
“map” = semen
“sauce” = orgy
The similarities were rather striking. One pizza place even changed their logo shortly after the comparisons were drawn. This only added more fuel to the fire. http://i.imgur.com/GIRxh8r.jpg
Myself being a huge fan of conspiracy theory I've seen this before: the minds become focussed on finding evidence, discarding Occam's razor, and mining for all the nuggets. What remains are coincidences that appear too good to be random. Compare with the "backwards playing record hidden messages" hype. Once someone points it out to you, your mind starts hearing it too.
P.S.: The "hashes" found in the .jpg images were a dead end / the result of pareidolia.
