What is the significance of 吃秋葵时过世?
It seems that that at some time dweg (or died while eating gumbo) has been used in English by some people. Although I can't find many references to it. The definition for dweg can be found on this website: http://www.abbrt.com/dweg

For some reason this ended up in the Comprehensive English-Chinese Dictionary which is one of the sources of Nciku. Nciku also has the definition for dweg and 吃秋葵时过世 is their tranlation of died while eating gumbo.

It is definitely not a Chinese expression and not something that is worthwhile learning.
