Gaslighting

There's no such thing as gaslighting. Who even told you about this word? You probably dreamt it up. You're so stupid for even thinking this could be a real word.

Gaslighting? Maybe you misremembered a different word?

gaslight 

When you use words to manipulate and trick people into thinking what they know is true is incorrect. The gaslighter uses tactics to make the listener selfdoubt and feel in the wrong. Often used by repeat offenders.

It's a secret!
But no seriously, Gaster is a secret character from the game UNDERTALE. Said to be Sans and Papyrus' dad. Well, it's not confirmed, but he may be. He speaks in WingDings too.
