Oh,we used to play this at high school. We tried to be as nasty and bizzare as possible, and when unveiling the result we would usually break out in hysterical laughter. Later I once played it at a Christian party - people were not amused...
a nice element of this game is that it can be played over time/doesn’t have to prevent other socialization at a party. If everyone understands how to play, you can set down/pick up the drawing at any time. Even if it’s an hour later, it is fun to see the results.
