"tame" to me, means that a snake can be handled and be in your physical presence without stress. My oldest male, is very "tame" in that I can pick him up, touch him, clean his hide, hang out with him, whatever, and he shows no signs of stress at all. It took a couple of years of us being around each other, but he is friendly with me, and fearless of me know.

That is all. these young hatchlings that I have recently acquired though... not tame, lol
