gas lighting 

1. to tell a bald faced lie to someone and then brazenly deny that this was ever done

2. to give a person the frustration of moving their keys, purse, wallet, condoms, or other object and to then claim they were never moved or the person had done it themself

3. a frequent tool in the slickery dick or slickery clit's toolkit for infidelity

4. an insidious tool in the hands of unscrupulous mind-screwers and sociopaths

5. to tell a lie (consciously or unconsciously) without regard for whether or not you undermine another person's sanity/ perception of reality

It comes from the 1938 movie Gas Light.

Tommy Lee was gas lighting Elizabeth Taylor until she lost her mind. Mr. Lee should be shot.

Courtney Love leveled Kurt Cobain, not just with the multiple affairs, but by gently undermining his self respect with a little known procedure called gas lighting. He didn't even know he was a pound overweight until he was 20 pounds overweight. Poor guy.

It is a sign of the slow progress of culture that something as insidious as gas lighting can fail to be widely known, except in a slang dictionary definition, nearly three quarters of a century later than the movie by the same name.

Gaslightning 

A form of intimidation or psychological abuse, sometimes called Ambient Abuse where false information is presented to the victim, making them doubt their own memory, perception and quite often, their sanity. Often erroneously called "gaslighting". The classic example of gaslightning is to switch something around on someone that you know they're sure to notice, but then deny knowing anything about it, and to explain that they "must be imagining things" when they challenge these changes.

A more psychological definition of gaslightning is "an increasing frequency of systematically withholding factual information from, and/or providing false information to, the victim - having the gradual effect of making them anxious, confused, and less able to trust their own memory and perception.

My husband tricked me into thinking it was called gaslighting when it's actually called gaslightning

Gas-lighting 

Attempting to deceive others about farting by switching types: silent but deadly, long and lingering, popping corn, bold and blatant, hidden behind other sounds and the sonic stinky. Ultimately driving everyone around him crazy and nauseous!

One of my strangest friends tends to pretend that he doesn’t have digestive gaseous problems by Gas-lighting his farts in different ways instead of just owning them!!!
