At what point of a relationship do you begin using terms of endearment (babe, honey, etc) on another person?

I'm curious when others start using terms of endearment/pet names. I use hun a lot even with people I don't know. It's just a southern thing for me. Sweetie and cutie might come out during the flirting phase. Anything else means I have feelings most likely but will use them even before dating.

If you have certain terms you'll use at certain times, explain those in the comments below.
I'll use them anytime, even before a friendship has formed
Friend stage, before romantic feelings have started
Flirting stage
After dating has started
Marriage
Other (explain in comments)
