HAHAHAHA!
You just discovered that you can out drink your snake!
Snakes don't hold liquids too well right after a drink.
I have seen owners freeking out over their snake leaking like this right after a drink and panicing cause they think the snake just got the worst
RI instantaneously. [img]modules/Forum/images/smiles/icon_eek.gif[/img]
I am going to say that since you saw it drinking and then it hissed and leaked that you startled him and he couldn't hold it down after the expulsion of his air and when his head went down to crawl, gravity took over and the water flowed downhill or out of him.
Nothing to worry about at all unless it becomes a habit or involves food.
