The game MASH is a friendly game played by preteens to predict each other's future. MASH is an abbreviation of Mansion, Apartment, Shack, and House. Players write MASH at the top of a paper and think of multiple categories such as cars, spouses, and pets. Each player thinks of two items for each category. One of the players draws a swirl until the player the MASH is about says to stop. The number of lines in the swirl are counted and each one of those items are crossed off the list. Play continues until there is only one row of items left. This is considered the player's future.

The plural of mash is mashes.
