While watching TV shows, I occasionally come across the phrase ‘remember this!’ in the context where one character gets wronged by another but couldn’t retaliate right away. How should I interpret this expression? Does it expand into ‘remember what you’ve done because I will get payback’ or it is closely to ‘I will remember this, and will get back at you for it’ or something else completely?
Here is an example: Person A is standing on a stage and decides to humorously mock/humiliate someone else in the presence of a huge audience. The person on the receiving end doesn’t want to lash out on the spot but insteads says ‘remember this!’ to person A as he walks down the stage.
