look up any word, like hipster:
noun: a heterosexual companion of the opposite sex with whom one spends a great deal of time and shares a deep level of comfort but has no intimate relations. Usually both members in a without benefits union are single. The relationship is also often characterized by sarcasm and other behaviors typical to a married couple who have been together many years.
I can't find a date to bring to the BBQ, so I will bring my spouse without benefits.
