nemophilies:

[…] lovers who touch each other with words, whose contact with each other is made of words, and who can thus repeat themselves without end, marveling at the utterly banal, because their speech is not a language, but an idiom they share with no other, and because each gazes at themselves in the other’s gaze in a redoubling which goes from mirage to admiration.” 

— Maurice Blanchot, The Writing of the Disaster

“The more familiar two people become, the more the language they speak together departs from that of the ordinary, dictionary-defined discourse. Familiarity creates a new language, an in-house language of intimacy that carries reference to the story the two lovers are weaving together and that cannot be readily understood by others.”

—  Alain de Botton, On Love
