Imagine selectively quoting AI to try and prove your point regarding a words meaning instead of a fucking dictionary. Pretty sure this is the second time you have been deliberately intellectually dishonest.
Since you lack any actual insight, it’s from a movie, and here’s the actual AI overview if you aren’t selectively looking quoting:
Gaslighting is a form of psychological manipulation where a person makes you question your own reality, sanity, or memories to gain control
. The term comes from the 1944 film Gaslight, where a husband manipulates his wife into believing she is going insane by secretly dimming gas-powered lights and denying it when she points it out.
