 The hair below the upper portion of the sides and back of the head is tapered short or semi-short with a clipper, in the same manner as a crew cut.A variant form may have a slight graduation of the top hair longer from back to front or a quickly graduated bit of hair at the front hairline to achieve a little flip up of the hair at the forehead.A butch that is cut at less than inch on top may be referred to as a burr.
