MOC
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. Because of this, MOC's are most commonly organized by South Asian gays and lesbians due to the traditional familial pressure to marry.
Girl 1: You know how it looks to the family, an unmarried Muslim girl in her late 20's. My parents say if I don't get married soon, they'll arrange one for me!

Girl 2: Why don't you just arrange an MOC with a gay guy?

If someone creates a nickname for you, teases you, acts nervous around you, tries to impress you, stares at you intently,makes conversation with you, flirts with you etcetera it is an MOC.
Anna: Did you see how Ben couldn't stop staring at Katie during drama and even asked her to work with him on the new assignment? Total MOC!
