The "You know (enter activity) too much if" game is the product of various blogging/message board occurrences.
Usually, one initaiates this post with a common obsession/interest of the group such as a video game, book, etc.
Here's an example of you know you... too much if.
You know you've been on Urbandictionary.com too much if:
-you check your email only to see if there are any new entries that day
-you make new entries to see how many people will give you a thumbs up
-you make an entry that explains the "you know you _____ too much if game"
You get it, right?
