Why did she call me "buddy"?

so a girl I had flirted with for a while, got grounded and couldn't talk to me for a week, when she got off of grounding, she talked to me again, this time saying "hey, what's up BUDDY"?

mind you, she used words like babe, and hun, before she was grounded... plus she did some other flirty stuff, that I don't want to mention, but

why did she say that? she knows I like her...
