Here’s my tip, don’t do it. A) you don’t stutter and the mechanics of what happens can not be duplicated naturally B) there are so many different facial/body ticks that happen when a person gets stuck. It’s not just one thing that happens And most importantly C) you don’t stutter, so it doesn’t matter what you say your intentions are, it is going to come off as you trying to get recognition and heighten yourself at the expense of people who have this disability and the fear and shame we experience every moment of our lives. Again, do not do it.
