Good effort but weak fact-checking. The fact that the term exists in informal dictionaries doesn't mean shit, if you don't analyse the context of the emails. You said pizza = girl and map = semen. So they found a handkerchief with girl-related semen on it? It doesn't make any sense. Also, cheese is not little girl and pasta is not little boy. You don't send a little boy in a box.

PS: I'm not a shill, but I think this list is very wrong.
