What we should call the first decade of the 2000's.
Oh-oh implies that a lot of stuff went really strangely, and surprisingly wrong, exactly what has happened.
- Dubya, climate change, terrorism, swine-flu, recession --> all pretty much an oh-oh decade.
"I haven't felt financially stable since the oh-ohs."
"Back in the oh-ohs, weird shit was happening every few months"
"The recession started in the late oh-ohs"
