Granted, I spelled it wrong, but I've been calling him Pootie for over 20 years now. It just stuck. And since he hates his real name anyway (Phillip), he adopted it and refers to himself as Pootie most of the time.
And that's the whole story behind "Pootie". Who also has green eyes and a nice laugh.
But who most assuredly does NOT call me "Bitsy" anything.
