I voted "Yes, more than once" - but I feel this question is a bit more complicated than the poll suggests... I think there is a "tagged by a BP" vs a "bit by a BP" difference. My bites have been defensive strikes where there is definitely an open mouth and strike, but usually just a bonk on the hand with the snout. In both cases, the snake never actually "bit" me, i.e., never closed down on my hand. I am learning that my cats are actually more detrimental to the health of my arm than my BPs...

BTW, these strikes occurred after a handling session trying to remove a bad shed - my little girl appears extra sensitive when dealing with stuck shed around her tail and vent area. I got a couple huffs and puffs, and then a definite "stop messing with me down there" strike.
