>>507856032Wrong.
The term is "gaslight" and it comes from a play and movie from the 1940's
The setting is in a time where gaslights were possible in the home.
In the movie some criminal guy marries a rich chick. They move from the country to the city where the criminal has been trying to find some big score of wealth (some gemstones) inside a home. he thinks its on an upper floor that nobody is supposed to go into.
The entire time he's trying to make this rich chick think she's losing her mind by making her think she's blacking out and hiding things around the house...I suppose that's for a secondary grift to get her committed to an asylum and he can have free reign of the wealth.
>that's all cool but where does 'gaslight' come from then?Well whenever the criminal guy is in the upper rooms of the house he is using the lights up there which makes the gas lights in the main part of the house go dim for a bit.
This is how they ultimately catch him once she starts talking to a cop friend about all of this shit and the cop is like
>you're not crazy. The lights are dimming because this dude is in the upper rooms even though he's saying he's not!and there you go.
The term has more to do with the title of the movie and what the dude is attempting to do than anything that actually happens regarding gaslights.
hell, the movie's title doesn't even have a whole lot to do with what's going on in the movie...its a minor detail.
