Meaning:
This Chinese character literally means “brilliant” or “to show off.” However, the character is used in the northeastern Chinese dialect to mean “to eat (or drink) greedily.” Some people explain that this character is in fact used mistakenly in the place of a homophone “楦” that means “to make full.” Like many other usages from the northeastern Chinese dialect, this character was quickly picked up by Chinese netizens for its humorous effect.
