How it's used
This term reflects a cultural practice of forming fictive kinship bonds between friends who share a close, brotherly connection. It implies a level of intimacy and loyalty that goes beyond casual friendship. While the bond is symbolic, it is often treated with the same social weight as a real family relationship.

Common phrases
to acknowledge someone as a sworn younger brother
Common mistake
Do not confuse this with a literal younger brother, which is simply 細佬. Using 契細佬 implies a specific, conscious decision to establish a formal sworn relationship, rather than just being close friends.
