她说我死老头子
[tā shuō wŏ sĭ lăo tóu zi]
This could suggest an interesting background - maybe there’s some banter or playful teasing in the relationship. 'Dead old man' means she is referring to someone as an old-fashioned guy, which implies he might not change according to new times and always keeps his own set rules. In some ways, it conveys fondness and intimacy as well as some mild complaint.
