"Maximize content, minimize words. I learned it in journalism school, but actually use it in improv. Say something in as few words as you can. Plenty of players will talk a ton, so if you don't have to you'll be twice as fun to play with. Plus you'll (hopefully) listen more, and that's where the magic is. Also, don't over-explain what you say! Give your scene partner the gift of misunderstanding you. Tell them "you look like a hat person" and let them decide what it means - weird head? Balding? Compliment? They decide, and you both win!"
