Today I had a Mock MUN meeting, and I was talking to a few of my friends out of my state (California) and they had no idea what MUN is which I was surprised about that.
MUN = Model United Nations. It can be a high school club/class where you are assigned a country and you have to research the countries view on a subject. Then you go to the conference where you represent the country and talk about the view of the country. You form alliances with similar views and you write a position paper which you try to convince people to vote for.
