Can your sanity (or complete lack thereof) be measured by the nicknames you have for your pet?

I remember when I first took Skeletor to dog training and Michael asked me my dog's name. I told him it was Skeletor, and he asked if he had a nickname (something with fewer syllables.) Melanie and I looked at each other and shrugged. We hardly ever call him Skelly in person, even though we use the name online quite often.

Thinking back on that conversation, I realized that I have many, many weird names I call him on a nearly constant basis. I don't use these names when I'm actually calling him mind you, but I say them enough that I'm sure he'd answer to just about any one. (I may have to test that theory)

So, without further ado, the many ridiculous nicknames of Skeletor. If you need me, I'll be getting settled into my straight jacket...

• Mr. Dog - the most popular by far. I can exactly pinpoint the origin of this nickname. It was when I was 10 years old. My stepdad's friend was visiting. He had a son who was a few years older than me. I remember being taken aback with how juvenile it sounded when the boy referred to a tomcat in our yard as "Mr. Cat." I referred to Insano as Mr. Cat for most of his life, and now Skeletor has become Mr. Dog. 
• Old Man - He's not really that old.. a young adult or a teenager really. However, his droopy pooch face makes him look like a grandpa. 
• Pup / Pooch - These ones are pretty standard issue...
• You Turd - A term of endearment that kinda means the same thing as you brat. I let it slip out on Melanie once and found out that she doesn't appreciate it one bit. 
• Doggy! - Another popular one. I'm pretty sure this has evolved from the show South Park when Cartman yells "no kitty! that's a bad kitty!"
• Doggo - This is actually a nickname I created for Sophie when she lived with us. I got a huge kick out of it when she started responding to "Doggo" - her owner Kim, wasn't quite as amused :) Since Sophie isn't around, Skeletor sometimes gets referred to as Doggo. 
• Buddy / Bud - When he's being good or acting pathetic, he'll get one of these praise-infused nicknames
• Senior - The origin here... it's kind of a cross between Mr. Dog and Old Man.
• Mister - Short for Mr. Dog. He gets this a lot when he's misbehaving... ahem... jumping on the couch or bed for example. 
• Hound - When I was in high school, I thought this word was funny for some unknown reason. Probably for the same reason I think a lot of words of German origin are funny. 
• Houndo - A cross between Doggo and Hound

So as you can see, I'm a crazy person. Post your bizarre pet nicknames in the comments so we can go to the nut house together!
