From TFA (the fine article):
As for the title: a CDO is a financial instrument that became pretty infamous during the financial crisis of 2007. An entertaining explanation of that can be found in “The Big Short”.
Its the last sentence of the article as a footnote with a wikipedia link to a page about CDO.

If you’re using an obscure acronym in your title, it deserves more than just a link in a footnote imo, but whatever
