@WhoopassGirl Names are a peculiar thing in and of themselves. Merely labels of sorts that we respond to.
I feel like it largely depends on whether or not the origin of the nickname is a point of pride or contention. It's less that they use it as it is how/why they use it, whether or not they're trying to imbed themselves closer to your inner circle, etc.
I'd likely just feel really uncomfortable depending. It's an intimacy thing.
