Double Ditto

Double Ditto from Pressman, is a party game for 4 or more players ages 10 and up and takes 15-30 minutes to play.

Take turns being the Ditto Master by reading a card out loud to the group. Players then have 15 seconds to write down two answers that come to mind. Once time is up, take turns reading the answers out loud, crossing off each answer that matches another player's answer.
The object of the game is to write down answers you think other players will write. Match an answer with another player to score a "ditto!" Match both answers and score a "double ditto!"
