Make a site that exists purely for your own amusement. Exclude the whole thing in robots.txt. Do not add it to gwt, author profiles or anything else. Do not bother about 403-level exclusions, except as needed to protect the server.
Use horrible colors and have the same content on all pages, including duplicate titles and meta tags. Bonus points if some pages are called "untitled" or "new page". Use tables for layout. Use the <font> tag liberally. Either have multiple <h1> on the same page, or have nothing higher than <h3>. Move, delete and rearrange pages every other week. Never code for any 301s or 410s.
Find a personally gratifying domain name. Mine's called google-plays-silly-buggers dot com. (It isn't really, but I consistently use this name when talking about it. Every week or so I get a human visitor from Bing search.*)
Oh, and you can use it to test things that you're not 100% sure can be done without crashing the site or sending php into a coma. But that's an optional extra. Your main goal is the guilty pleasure of looking at "Welcome to my Garbage Site" in lurid magenta text on a cyan background.
That last bit was an exaggeration. My background is black-- but only because I occasionally use the pages for testing, and my optometrist makes enough money already.
Wasn't that fun?
