I was told as a kid it's to shove a hose up its ass not just anything lying around or your fingers. You may get lucky as it might let go from it just being weirded out about you fingering it's ass, but a hose up anyone's ass will result in death if done for long enough wouldn't it? But then you'd have to be conveniently near a hose in an attack situation. Best bet is to choke it out, shove your fingers or objects in to its eyes and up its nose or hit it right on the dent in their skull to knock it out/kill it. When you see videos of people just hitting and kicking them, it only passes them of more and will make them hold on even tighter, there's no reasoning with them they're like niggers
