Traitor Word

From BoardGameGeek:

Can you say the right things in Traitor Word and not be caught - or trick someone into accusing you of trying to do this? Each player gets a handful of word cards, with each card featuring two words. Choose a start player, then flip a card from the deck to determine the starting word. The start player has a bit of time to say a single word that's related to the starting word, then the next player must say a word related to the first player's word, and so on. Ideally a player can say a word on one of their cards. If they do - and no one has accused them of doing so by their next turn - the player reveals the card showing this word, then scores it for 1 point. If someone correctly accuses a player of saying a word held by that player, then the accuser scores that card as 1 point; if the accusation was wrong, then the accused scores 1 point. The first player to collect 5 points wins.
