What is this game called?

so this isn’t an actual board game, but I don’t know what sub Reddit to use. So in this game, there’s something like a ’host’ who chooses a question and gives it to everyone but one person who get to different question and is called the impostor. Then everyone takes turns at showing their board and once they all show their board the host reveals the question. Everyone then has to defend the answer and after two minutes they choose who the impostor was. What is this game and if you don’t know the name of the game, can you please leave some of questions you could use?
