A term invented by HG Tudor, famous NPD author, proving that imitation is NOT, in fact, the sincerest form of flattery. Instead it's the preferred method of destruction for a narcissist to try and steal everything
good about you like the mythological Ape of Thoth. They are trying to steal your place at the
table in life, your professional/private destiny and social
karma. It is a theft of your erotic capital, unique personal style, idiolect or manner of speech, intellectual capital, social capital including hobbies etc. It's giving Single White Female but this can happen to anybody, from anyone else, including cultural appropriation from any outgroup racially, sexually or generic outsider in class. It continues until they steal the
target's life including spouse and
friends or they are exposed for being too blatant or possibly, rarely, find another juicier
target or can no longer access the original
target, like being blocked. Paper trails are useful with these types of
people because they
will project whatever they are doing onto you, always be the first to publish something of yours, never let them see or edit anything. Never tell them your plans, even something frivolous and simple like your intended outfits and favourite restaurants. Stay vague and go Grey Rock to survive. Do not let them interrogate you on your life, beliefs, plans, dreams, crushes etc.
