What is among us dead body?

In the game Among Us, when a player's character is killed by the impostor, their character becomes a dead body. The dead body can no longer interact with the game and is no longer able to communicate with the other players. The body is left where it was killed until a living player reports it, or until another player comes across it and reports it themselves. Reporting a dead body triggers a meeting where the players discuss who they think the impostor is and vote to eject a player from the game. It is important to report dead bodies and not leave them unnoticed as it could potentially lead to the impostor winning the game.
