The term "hot mess" (http://www.urbandictionary.com/define.php?term=hot+mess) was popularized on one of my favorite shows, Project Runway. It means a person is a real mess, or a combination of hot and a mess at the same time--a contradiction.
I can't think of a more apt term for the edgy, odd posts in this blog.
I happen to love hot fudge sundaes, so "hot mess sundae" is kind of tribute to the ultimate hot mess. 8)
