1. Comment and I'll tell you what stuff I associate with you. This can mean (Matt's suggestion) 'what games you play' or 'what bands you love'; it could mean 'What thing you have said is most "you" to me?' It could be pure guessing on my part: "Ooo! You do macrame!" But you'll get some variation of "When I think of you, I think of __________."
2. Post this in your own journal so I can see what stuff you associate with me.
So, onward...
