Okay, 'fess up...who besides me calls their piggies by silly knicknames?
Amy is either Sweetcheeks or Girlfriend (not sure where the first one came from, but the second was my nickname for Borat when he was known as Leela because he'd been missexed, so it carried over to Amy).
Borat is either Bo, Boooow-rat (with the first part drawn out), or Rat Boy.
When Amy chomped hubby's finger, he dubbed her with yet another nickname: Witchley (but substitute a B for the W). That was originally the nickname of a mare at the barn where I kept Cochise; she was great to ride but a demon to handle. Hubby actually learned to ride on her.
