I'd love to have someone to whisper pet names to 
 
 That being said it would probably be something fitted to who they are, maybe a favorite food, or related to something interesting, in addition to sweetie, baby, honey, cupcake.  Something we both found adorable that was related to her.  Maybe if they were feisty I could call them my little firecracker 

 hahaha.
I've had some interesting pet names thrown my way though by women I was good friends with.  The weirdest one I think I got was child.
