who is excessively proud
of his masculinity
; especially one who expresses this pride to the detriment of women
Male chauvinism is not the same as misogyny, though both are forms of sexism. In misogyny, the afflicted person feels explicit hatred or hostility towards women. A male chauvinist, on the other hand, may feel no ill will towards women; he may merely thoughtlessly ignore the needs or interests of women in his life while pursuing his esteemed "masculine" activities.
Whereas both men and women can be misogynists (or misandrists), only a man can be a male chauvinist: Chauvinism refers to excessive pride in some group to which one belongs; it originally referred to a mindless species of patriotism which we might now call jingoism.
