Illegally give flowers
From China Digital Space
非法献花(fēi fǎ xiàn huā): illegal dedication of flowers
After Google announced it was pulling out of China, a number of people dedicated flowers in front of the Google headquarters in China. Some of these people were dispersed by security guards who alleged that what they were doing amounted to the “illegal dedication of flowers.” Because the charge was so made-up sounding, it quickly spread around the web and inspired the terms that follow.
非法吃喝(fēi fǎ chī hē): illegal eating and drinking
This term was created when users of Twitter (which is blocked in China) met together to discuss the imprisonment of three netizens in Fujian. DSD agents broke up the meeting and accused those present of “illegal eating and drinking.” See, here.
