Occupy Wall Street Movement 

What you have when you take a dump in public (especially on a police car) in NYC and no one arrests you. It tends to show a definitive lack of respect for anyone and anything in the immediate area.

Man-on-the-Street: Oh my god, that hippie over there is taking a dump right in the middle of that fountain!

Mayor Bloomberg: Don't worry, he's just having his Occupy Wall Street movement.

Occupy Wall Street movement 

A series of protests of concerned U.S. citizens, mostly held in New York City, to end the corporate greed and political corruption that has been degrading democracy in this country for years.
Criticized by the largely corporate-controlled media (Fox News especially), but is still gaining ground and will (hopefully) meet their goal of restoring the power to the people, not just the wealthiest 1% of Americans.

The Occupy Wall Street movement is opposite of the Tea Party protests.
