How it's used
This term originates from the traditional custom of 上契, where a person formally enters a godparent relationship or establishes a sibling bond with someone outside their biological family. It carries a sense of genuine familial closeness rather than just a casual friendship. In modern usage, it is sometimes used to describe a close male friend who acts like a protective brother, though it still implies a formal recognition of that bond.

to enter into a sworn sibling or godparent relationship
Common mistake
Do not confuse this with 哥哥, which refers strictly to a biological elder brother. Using 契哥 for a biological brother is incorrect and would cause confusion about the family structure.
