ELI5: What is passive aggressive behaviour?
gpt
It is behavior meant to antagonize someone indirectly.

For example: Let's say you have an assigned parking spot and someone else takes it. Normal - "aggressive" - behavior would be to find the person and address them directly about the issue. Passive aggressive behavior would be to retaliate in a subtle fashion, such as parking on the left side, leaving no room for them to open the door.

The goal of each is the same: to eliminate some unwanted behavior of another party. However, passive aggressive behavior tries to do this without a direct confrontation, ideally without having to speak or interact to other parties about the issue, avoiding direct confrontation. Because of this it is usually inefficient, since the other party may not even be aware of what it is they are doing wrong, but will probably be very aware of your attempts to antagonize them, escalating, rather than resolving the conflict.
