Bobbit?
Close! Funny story, (well, to me) about my ex-husband losing a digit in an industrial accident. I worked in the hospital where he had his surgery, and we were getting post-op instructions when the ER doc that I worked with the most walked by.
Since his arm was held at waist level, and he's a huge guy, the pinkie finger was sort of below his waist.
without a beat, the doc kept walking and muttered "Missed it by this much......." and "you're no bobbit". But the girls at work still call me "Bobbit".
