See #2 ... Oh, wait... https://dictionary.cambridge.org/dictionary/english/gaslighting

But yes, I get it. That's the reason why this is so frustrating. At this point gaslighting has become synonymous with deceiving. Because people who use the word don't know the (original) meaning!

The secondary definition is for dipshits who heard this term, didn't understand, and misused it for so long, mirriam webster added the colloquial usage*. In short: you are a smug dipshit.

Edit: I have a learning disability.

See #2 for why that isn’t a good argument. Dictionaries describe common usage, even when that usage is/was just litterally wrong. If I made a meme with that used the second definition of literally people would be right to point out that it would be much better to use the first. In this meme’s case it also just furthers the misunderstanding of the term gaslighting.
