Ok I never log on because commenting is cringe in 2021 but I thought I’d share a few ideas of what I remember.

To clarify I have no idea what movie it is…..

I’m not sure the exact saying is “that’s for almost getting us killed”

It seems more familiar that she says slap “that’s for lying to me” kiss “that’s for saving my life”

And it happened right after the slap because from what I can remember about this specific scene is right before when the action was happening and the ‘hero’ saved her life she also find out he had been lying about something else during the action event of the movie. Idk maybe that sounds way off….but I remember those exact similar quotes (whether she slaps because of lying or almost getting killed) also….this kind of concept pops up in different movies but in this specific one that the OP is mentioning is definitely something Iv seen.
