A competition where you have to strike fear into the audience. The one who does it better wins. It has some restrictions as to avoid severe injuries or cause death. It is a sport that isn't that well known but it is quite entertaining to take part in as one of the contestants. I was once among the audience and I had to go to therapy for 3 years. *Never again*.
Person A:"Hey wanna play Among Us today?"
Person B:"Sorry, I can't. I have a few hours competitive terrorism today."
