How it's used
Originally a concept from traditional Chinese medicine describing an imbalance of bodily energies, this idiom is now frequently used in casual conversation to describe social or workplace environments where females significantly outnumber males. It carries a slightly playful or observational tone rather than a medical one. It is common to hear it used when commenting on the gender ratio of a specific department, social group, or academic major.

Common mistake
Avoid using this term in serious medical contexts unless you are specifically discussing traditional Chinese medicine, as it will sound confusing or out of place to most listeners who only know the social meaning.
