What is the definition of Yearly Weapon?

A 'yearly weapon' is like a super-powered, yet ridiculously mundane, tool of terror that's used once a year, usually by the government or an overzealous superhero. Picture it: a yearly 'National Day of Silence Against Bullying' or a 'World Day of Peacefully Executing Crayons'.
