I just saw someone say the words "jokingly gaslight" this might be a good time to reintroduce the internet to the terms "lying" or perhaps "pranking" or even just "joking" on it's own
Okay, say it with me guys…
If you are giving someone wrong information in the hopes that they'll believe that it's true, then that's lying.
If you are giving someone wrong information under the assumption that they'll ultimately realise that it's false, and that they will find this funny, then that's joking.
If you are giving someone wrong information in the hopes that they'll believe that it's true and that their response will be funny, then that's a prank.
If you are giving someone wrong information in the hopes that they will notice the differences between your presentation of reality and their perception of it, and come to doubt their ability to judge what is and is not real, then that's gaslighting.
