“咱们今晚去腐败，好不好？”

My co-worker asks me if I want to go fubai （腐败）with him tonight. I am utterly confused, because as a Chinese student I learned that the word fubai is generally used to describe corrupt government officials.

There is a new definition of the word spreading around the BBS message boards. Online, fubai (abbreviated FB) most often refers to a group of friends who go out for a big expensive meal. My colleague did not ask me to go with him to exchange red envelopes full of cash with government officials; he just wanted me to go with him to an expensive Japanese buffet restaurant for dinner.
Some examples of new age fubai:

Exhibit A: A Chinese netizen posts a picture of her afternoon tea at Pizza Hut. In the US Pizza Hut is cheap fast food, but in China it is the perfect fubai treat.

Exhibit B: A Beijing University online forum dedicated solely to documenting Beijing’s best ways to fubai:
