My sugar, my sweetie, my oxygen

I call my man my sugar because I am a classic southern bell and as any southerner knows, most women in the deep south calls anyone who means anything to them sugar. It's a term of indearment. Him, being flighty sometimes, will call me anything from babycakes to his sugar mama. It's not necessarily what he calls me or what I call him, but how we say it and the tone of voice.
