Masculine of center (MoC), which, in its evolving definition, recognizes the cultural breadth and depth of identity for lesbian/queer women and gender nonconforming/trans people who tilt toward the masculine side of the gender spectrum, including a wide range of identities such as butch, stud, non-binary, transgender, genderqueer, androgynous, transmasculine, boi, etc. Very similar in meaning to transmasculine.

The term was coined by B. Cole of the Brown Boi Project.

Literally everyone, ever. Including the writer of this definition.
