Sacred Haven of Debauchery

The key to "wittiness" implies communication based on the situation. For example, you're walking down the street with a girl and see a bus with a sushi advertisement. You can ask if she likes sushi, and then the conversation might shift to Japan, from Japan to earthquakes, and so on. In other words, the conversation is structured in the same way a tree grows – a trunk grows, branches sprout from it, more branches grow from those branches, and so on, branching out to form a crown. Thus, your conversation path goes from the trunk to the thinnest twig, and the entire crown with thousands of twigs represents your conversation possibilities.
