    All according to *keikaku*

    (TN: keikaku means plan)

This meme comes from the overuse of TNs in anime fansubs to explain obvious things, things that did not need explaining, or where there would be a perfectly straightforward English word that would do the job.

Neologisms: do you mean neologism in the source language or the target language? This usually happens in the other direction, where the English words for things get copied straight over to other languages to refer to new items. There must be examples in the other direction but I can't immediately think of one.
