Just One

You work together as a group to help one person guess a secret word. Everyone writes down a single clue word on their whiteboard. Before the guesser looks, you compare your clues. If two people wrote the exact same word, those clues are erased. You have to try and think of a clue that is helpful but not so obvious that someone else will write it too. It is extremely simple to explain and usually generates a lot of laughs. A reliable filler game for any casual social gathering.
