Girls, If a 6 year older woman calls you her bunny what can I take out of this, is this a positive take or a negative?

So i know her for 5 years from my childhood friend at his house and she is a childhood friend of my friend’s sister, she seems little shy around me and whenever she or me drive each other home she say’s goodbye and adds „my bunny“ recently.

i still cannot figure if she has somewhat feelings for me or me overthinking about us.

Also, i would like to point out her being German and me being from the Netherlands.

I think it gives a important perspective since it maybe mean differently across other countries of this world, nonetheless i would like to know your opinions.
