(n.) A state of eternal friendship between two bros. Two bros entering into a bromarriage have probably shared many experiences such as hometowns, colleges, or sexual partners. Bromarriages usually originate through Greek brotherhood, childhood-to-adult friendships, or teammate relationships. There are polybromarriages but it is uncommon that all bros have equal bonds.
