As the title suggests you ask a question and the person has to answer which they prefer over the other.
"Coffee or tea?"
The next person has to reply with either coffee or tea or just simply say neither. Keep the game going by asking another question. It can be just about anything from dramas to actors to whether or not you want to know if the next person likes pineapple on pizza or not.
I will start: Morning showers or night showers?
