Dellbell: the only person who calls me this, and is allowed to call me this, is Moni. I ruv her!
Dell: stock-standard, for anyone too lazy to add on the last syllable.
There are also about a million that Tom has for me, including but not limited to, Freckles, Pumpkin, Cupcake and Muffin.
I'm pretty happy with Della, truthfully.
