Benjamin, extreme nerd, just acronym-mad — it's nothing.

The acronym as we know it was invented at Bell Labs in the 1960s, but something similar has existed in Hebrew since Talmudic times. An autistic savant with somewhat of a Jewish upbringing might have come up with something of the sort (only, why in English?). If the acronym is used in the novel, which it may well not be, it will be Joshua's invention, and he won't be satisfied with it, so we'll probably see multiple versions.
