This answer isn’t much fun, but I believe the real estate crash will probably be blamed on and named after the “event” that causes it. For example, the stock market crash 0f 2001 is frequently blamed on 9-11 even though it began well before the world trade center attacks. People I work with go so far as to refer to the stock market crash as 9-11.
The Bird-flu-scare crash or Oil-shortage crash could be boring candidates, but you never know what the next cause will be blamed on.
I vote for the Tom-Hanks-didn’t-get-an-Oscar-this-year-because-the-Davinci-Code-sucked-induced-recession causing the real-estate market panic of 2007.
