I've also created a pick up game with my friends. We call it "Who's Opener is it Anyway?" I got the idea from Style who says you can make an opener out of virtually anything (which is how he came up with the flossing opener).
Anyway, the whole game is you take turns getting a topic from the group. As soon as you hear the word, you approach a set and deliver an opener using the topic. The outcome doesn't matter so much here - it's just fun to see how clever you can be in the 5-10 seconds before you open your mouth.
The group can be as difficult as they want. One of the most difficult topics I got was "Whiskey Dick." Yeah, fun times!
