Ghost is a written or spoken word game in which players take turns adding letters to a growing word fragment, trying not to be the one to complete a valid word. Grab some friends and play it here: https://literal-rorquals.itch.io/ghost-game

In Ghost Game you must make sure that the next player can form a word by adding another letter. That is, there’s at least one valid, longer word that can be formed after your turn is done. If you fail to do so you lose a point and the next round starts.
