Snakes are cool

. I've not heard of that kind before *looks up picture*.
As for constrictors, I think your friend just has one with a mind of its own (snakes have personalities too I've found, even if they're not as complex as, say, parrots). This is why you should never put a snake around your neck. He ought to try putting the snake in some warm water and see if that loosens its grip, before doing anything drastic
