The actual definition of a feminist is one who believes that women should be treated as the equals of men in all (reasonable) things and vice versa. Women who believe that women are better than men and claim to be feminists (the ones that give feminism a bad name) are actually chauvinists (see chauvinism).

To answer a commonly asked question; can men be feminists? The answer is yes. I am not an activist, but I still believe all people are the same regardless of sex or nationality, thus I am a feminist by definition.
