I only do it towards my guy friends but it's just playfulness.
They give me a lot of nicknames, maybe try thinking of something that matches her personality.

Only ever called one guy that...mainly because of that song by usher and keys. it was because of affection and how much I cared for him.

It means she's into you sexually/ romantically. Call her a cute name back if you're also interested in her in that way
