This warm-up works like the classic party game Charades.
A player receives a simple, easy-to-guess term from the facilitator (ideally a compound word or a well-known title). The facilitator also names the category (e.g. movie, book, proverb).
The twist: the guessers deliberately misinterpret the pantomime, guessing everything except the obvious answer. This creates hilarious wrong guesses and trains creative thinking.
