Here in the south, you get a lot of pet names. Every waitress calls you "honey" or "sweety". I'm sure everyone is familiar with that concept. I've taken it upon myself to refer to all my friends as "pumpkin" or "puddin' ".
I also say "What's up, buttercup?" to all my female friends, but that appears to be me and not a regional thing.
I also still use "later 'gator", but that's because I'm a goober.
