What does it mean when a guy calls you feisty?

This was a while ago probably like 2 years ago. And I was hanging out with some friends in a tent because it was sorta sprinkling and that's just what we did. And this guy and his little bro always played football like in that area and that day his little bro was like "bothering" us and the older brother said "watch out with this one she's feisty" while pointing at me and then he smiled and looked away. What does he mean? What does this mean?
