Time to build an elaborate (and false) reasoning to share, and at the end of the story reveal the truth.

Naptha is the name of a character in Thomas Mann's https://en.wikipedia.org/wiki/The_Magic_Mountain

Naphta, actually, but the allusion to Thomas Mann's Nobel Prize winning book is brilliant in any case. Now there's whole pool of literary names that can be attached to future features, product roll-outs, etc.

Project Pepercorn alone is enough to get Business Insider writing about it all the time.
