I call the snake's nose a 'snoot' (I think that term actually came from this site while I was originally doing research), which leads to him being called "cute snoot" far more often than using his full name, Mashadar.

Also, (not for ball pythons) but when I'm training birds of prey I refer to pinky mice as 'popcorn' and the bowl of warm water used to thaw out the mice out as 'the hot tub'
