It's exactly what you think it is. I had some sloppy joe meat leftover one day and decided to make a pizza out of it. Good times, kids. The cheese is a mix of mozzarella and cheddar and I tossed some onion on there because I had some. Was it wicked good? Why yes it was, thanks for asking.
Heh, my girlfriend has referred to my pizza making style as "anything goes" which I think think is a perfectly good description. I'll put pretty much anything on some dough and top it with cheese. How about you guys, whats the weirdest thing you've put or had on pizza?
