In many cultures, the fox is considered a cunning animal, a "trickster." It can also symbolize an attractive yet secretive being, like the 'Gumiho' from Korean folklore.

Recently, it's used more often to positively describe a sensible and charming person, rather than in its negative sense of being sly. In particular, people with sharp eyes and a chic charm, like K-pop idols, are sometimes called "fox-like."
