I call my wife dietka, which is Russian for baby, she calls me Marcha or Marchello.
I also call her bashka sometimes, though I don’t know why.
Believe it or not, Butthead is a term of endearment my wife and I both use. I also call her Shithead, Swivelhips, and Legs.
My daughter is usually Slowpoke.

Those nicknames that I have not related to my name:
Muta, mutita, mutín, brujilla, puercaza, and cocoon are the ones my family use.
Caramela was a nickname formed by one classmate back in junior high. My last name sounds similar, and he called me that.
My family got a wonderful golden retriever at the pound at a young age. He was already named from his brief previous owner: Rizzoulli. He looked like a Rizzoulli, so we kept it. Called him Rizzy for short.
Any italian or italian-american dopers out there that can give some insight into what it means?
I call Gunslinger, who is my fiancé, sugarbee.
He calls me duckydoodle.

Ashes - (okey dokie, corny but I was smokin’ and the ashes in the tray reminded me of his color)
Hawthorn - named after the street I found him on
Shiva - the Goddess of DESTRUCTION - it fits
Toolbit - he belonged to my uncle, a machinist for NASCAR. After my uncle passed away my mother inherited the him . Shortly afterward, my mother wanted to call him PussyWillow. “Willow” for short. I went ballistic and eventually adopted him.
Blue Balls - a stray - he used to hump my leg (i swear)
I delivered a pizza to this family with a 3 year old girl. Their cocker spaniel was barking and she yells out in a beautiful 3 year old girl voice: “Be quiet Bananas”. My heart melted because I knew for sure that they got the dog and let the little girl name her.
I’m a baseball fan and have a Boston Terrier so of course his name is Fenway.
I had a cat once, found wandering for a long time in a friend’s apt complex, already neutered. I called him “Cinco” which was shorthand for “sin cojones.”
Is this thread supposed to be about interesting names for pets, or interesting pet names for people?
I did call my son “Droolio Iglesias” when he was a baby.
Hers- “Pierre” (does anyone remember the book “I don’t care, Pierre”?), “PD” (short for puppy dog), or more often the less creative “Baby Doll”
Mine is “Pale Fox”. I had an ex that called me “Boodah Bear”.
I still call my sisters “Butt Monkey”, but now it’s no longer an insult.
I named my last cat Dammit. Useful, versatile, and he always listened to me when I said his name.

My g/f and I call each other “arsehole”.
I’ve decided my next three pets will be Carrie, Meg, and Fawn, for “Charismatic Mega-Fauna.”
My ex called me “the brainless little onion ring.” I really wish I could remember the story behind that one. I don’t think it was as strange or kinky as it might sound. 
Payton, named after the greatest running back in NFL history, Walter “Sweetness” Payton. AKA: Payton el Bun, The Prince of Bunnies, The Duke of Adoreableness, The Czar of Cuteness, Fur-Face, The Trisket Monster
Fairly unoriginal and not having anything to do with her name, my girlfriend’s pet name is bunny. As it turns out, she does look a little like a bunnyface, and her nose scrunches up like one:)
When I first started calling her this, it was a bit more complicated, as her MSN name reveals: “cute little bunny rabbit girlface”. After a day or two that became bunny (occasionally bunnyface).
Interestingly enough, my mom occasionally signs things to my dad “yr bunnit”. No, I was not thinking of that when “cute little bunny rabbit girlface” came to mind.
I too, am fairly unoriginal when it comes to pet names. I just call my boy Paddy. Or if I’m feeling particularly cutsie or bunnyish, I’ll call him Paddycake. When I miss him he’s my cupcake.
You know…now that I think about it…my dad’s nickname for my step mom is ‘honey bunny’. I can’t believe it took me this long to remember it. Eep! scrunches up her nose
Have a cat named Buckethead. Had a dog named Radical. Another cat named Can’t Find Her.
Husband is Porkchop.
The Offspring is called “Bunting” or sometimes “The Bunting” from the nursery rhyme “Bye Baby Bunting.” This evolved into Bundt Cake which sometimes turns into Cake of my Heart. Sometimes she is called Oigle or Oigle Face, which is what my mother-in-law called cute little kids.
Some of my friends call me Mistress Ballista. Don’t ask.
