Occupy Wall Street (read: “skip classes; someone else is paying for it anyway”).

Select generic slogan that would be just as meaningful applied to Congress, unions, or any local school board (“no more corruption”).

Use Google Translate to convert idiomatic English into ungrammatical Chinese that means something entirely different (“not corrupted any more”), and scrawl the resulting Hanzi characters onto a poster with a marker.

Feel proud of this dubious accomplishment.
