Trimmer's Target is a term used to describe the goal of a person who trims or cuts hair. The term FAT is an acronym for 'Fade and Taper, ' which is a popular technique used by barbers and stylists to give a clean, sharp look to a haircut. This technique involves cutting the hair in layers, with the longest layer at the top and the shortest layer at the bottom. The goal of the trimmer is to create a smooth transition between the layers, resulting in a neat and stylish look.
