Where it comes from
Coined by American author and neologist John Koenig in 2013, creator of The Dictionary of Obscure Sorrows, with reference to Latin andronitis, described by him as a "hallway connecting the front part of the house with a complex inner atrium" in Ancient Roman architecture. According to Koenig, "one quirk of Roman houses" is that front rooms generally have Greek names while back rooms have Latin names, something he saw as characteristic of "your outer self and your inner self […] speaking in completely different languages."
