quasi-husband. A term that is for a long-term significant other or domestic partner (male), often cohabiting, who is too serious to be called a "boyfriend" but yet does not qualify to be called a husband according to the legal definition of traditional marriage.
Please RSVP for me+1. I will be bringing my quasband James.
Oh, Maria and her quasband Rob have been together for almost 8 years now. They just bought a house.
