What's In a Pet's Name?

There seems to be a lot of hunters roaming the lands of Azeroth, with all kinds of companions.  Crabs, wolves, cats, crocolisks, dinosaurs and plenty other types of creaturs abound.  These pets have various names.  Some are simple, like Turtle for turtle (if the player doesn't rename the pet, it's named for the type of animal it is).  Other names range from the funny to borderline obscene.  Why do players who do name their pets name them as they do?  It's based on individual taste of course.  My pets have names that hold sentimental value.  I only have three pets currently.  They are:

Rascal: Wolf.  This is the pet I run with the most.  I named this one after my late dog in real life who we put down a couple years ago after having her for 16 years.  She was a trusty hiking partner, car passenger, and always greeted me when I returned home from school.  Though WoW Rascal is only a bunch of pixels, I feel like the real Rascal is adventuring with me in spirit.

Killer: Cat.  A starter hunter pet from Teldrassil.  My first pet.  Killer is the nickname for my cat in RL who, and not to provide gory details, likes to leave presents on our front door.  I usually find a mess on the front porch when I head out to work...  Killer in WoW though chases after game much  more imposing than mice or chipmunks.

Housatonic: Turtle.  I don't use Housatonic often, but it's pretty cool to roam around with a turtle trailing you.  Housatonic is named for the river that starts its journey in the Berkshires of MA, runs down through Connecticut to the Long Island Sound.  I spent many summers at the Housatonic boating, waterskiing, tubing, swimming, and louging under the sun by the river bank.  Those summer days were great... 

If any players come across this blog who are of the hunter class, what goes into naming your pets?
