(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.
Taylor is getting married this weekend, Martin is his best man. It's about time they finally make the bromarriage official.
