干饭
gànfàn
Literally says
to attack the rice
Actually means
to eat with full commitment, to chow down like it is a mission
When to say it
Born in gaming slang, now the word for eating with total focus and joy. Shout gànfàn le when the food arrives, or call your hungriest friend a gànfànrén. Energetic, silly, perfect with friends at lunch.
Hear it in the wild
