Over a long period of time a person makes someone question who they are and if they are worth it. A person often questions themselves if they are the reason the person it like this. Form of abuse. Manipulating a person to think they are worthless, crazy, insane, mad and always in the wrong.
"Bob is always being manipulated by him."
"This has been going on for Years, and he always asks if he's the reason why they're in this mess"
"Yeah, I told you and Bob, its gaslighting."

When you fart into a lit match and it explodes
I had like 4 bowls of chili at Rick's Superbowl party. The resulting fart was brilliant, as was the size of the flame it produced. A proper halftime gaslighting.
