Plead the fifth meaning in this context?

I know if someone says I plead the fifth that means I’m choosing not to answer or remaining silent. Freedom to say nothing at all. Now when used in a flirty conversation… if someone says I plead the fifth does that usually mean the answer if affirmative? For example: (after a flirting conversation about liking one another) “you can’t tell me I’m wrong” “I plead the 5th.” Is that him saying yep, I like you but I’m not saying it lol
