Could it, maybe? The point is, who would let it squeeze to the point of passing out...
Its like one time, this guy calls our store and is like "My cal king swallowed my friend's finger, what should I do?" I couldn't help but think... how did you let a 3 foot cal king go all the way down your finger?? They aren't that strong or fast. Same thing with constricting... just pull it off if it starts squeezing too hard, I've done it with 6 foot boas for cryin out loud.
