Commonly used as an acronym for a (m)arriage (o)f (c)onvenience. A marriage of convenience, as the name suggests, is not a love marriage but instead, arranged in order to gain proper credentials to reside in a certain country (visas) or to conceal the fact that one is gay/lesbian from their family.
