Defecation: Defense mechanism or pure fear?

My bp has pooped on me once, but I think she literally just had to poop and it came out lol.

On the other hand, my milk snake truly musks within seconds of being touched every time and you can feel every bit of hate emanating from her body as she does it. And then she bites you and doesn't let go.

Snakes can say a lot without ever using words. Milk snakes are similar to king snakes- & even more high-strung, typically. I've had a few in the past- beautiful but usually flighty, & it takes a lot of patience to get them to accept handling without "special effects".
