Does anybody else stutter on purpose to watch the other person's reaction?

Does anybody else stutter on purpose to watch the other person's reaction? I am a high school senior and i have stuttered by entire life. I have a moderate to severe stutter. Sometimes when i am meeting new people i stutter really bad on purpose to judge their reaction. Based on that i will decide weather I will want to continue talking to them or to just break off the conversation. Keep in mind I am 6'4 and 250 pounds so i tend to tower over most people.
