I don't like my partner's suggested names for children, so I've been naming things she doesn't like with those name so they get taken off her list.
Why wouldn't you just tell her you don' like those names?
She's wrong with the baby names (letting me having an influence on it isnt enough, she wants to make rule like no year name like 1676 she thinks I will agree with her because she made me breakfast)
Naming children is a big decision, so it's something you and your partner should agree on. By passive-aggressively showing you don't like her choices, you could be frustrating your partner. Sit down and make a list of name you both like instead of causing fights over the names.
I want to talk about it with her, but she won't accept me doing it in playful way.
Then don't do it in a childish way. She might think that you are not ready for children if you cannot agree with her and start playing around.
