Have been struggling with definitions and have come up with these two.
Will appreciate the criticism.

A “white knight” is a man who doesn’t give two cents for feminism but is willing to engage in cultural me-tooism, usually in a position of power, most frequently a politician or an academic or having some kind of cultural weight who, seeing himself as a pragmatist, is willing to throw other men and society’s future under the bus of social justice and feminazism in order to obtain the gains that will benefit him personally. The “white knight” acts as the savior and protector of females regardless of the harm to other men and mankind.

A “mangina” is a weak man, often quite pussy-whipped, who craves female approval and validation and who pretends to enthusiastically defend feminism in the hope that this will gain him sexual points in the eyes of the females around him. He probably believes in feminism outright or ends up convincing himself of its falsehoods. He’s the first to jump hysterically against any real or perceived slight against femalehood, He is the most feminist animal in any group including any feminist females present. He often accuses other men of “misogyny” He should be understood as the ‘useful idiot’ for feminism. He usually gains nothing from females who see through his pretense and consider him as almost gay and low in the sexual totem pole if he gets to be part of it, at all. The “mangina” acts as a humble servant of females and can be thought, maybe figuratively, as willing to throw himself over a puddle so females can step on him to avoid getting mud on their shoes.
