were you talking to baloneyflaps?
Depends on what kind of definition you are looking for. In other words define 'definition'.
Masculine is an adjective, so you want the definition of a word that differentiates another word as distinct from something else (adjectives dont meet the rigor of a description).
So technically that would be a stipulative definition. Meaning that it has the meaning the speaker wants for the purpose of their discourse.
The context of your post puts the definition as something you are not.
So you answered your own question and your post fails the rigor test for philosophical questions.
