Captain Vagina 

A man loudly claiming to be a feminist who will fight gallantly in arguing women's issues that have nothing to do with him, often for the sole purpose of getting sex. Very often beta male types.

He's just playing Captain Vagina because he has no other way of getting laid

Captain Vagina 

A guy who just had his first Sex-Ed class and thinks it's ok to say vagina.

Dude 1: Awsome! I can say vagina now without getting yelled at.

Dude 2: Man, you're being such a Captain Vagina.
