Someone who fails to cover up that they're not a simp. They try to act manly and alpha-like but end up crumbling in front of a woman. Simpostors usually attempt to hide their secret from everyone. Some may last longer than others. Another definition of Simpostor is when a person simps so much in Among Us that they try to lie-low as much as possible and end up losing the game.
