White Knight
From lurkmore wiki
A white knight is a faggot who tries to "defend" whores, in hopes to get e-laid. White knights are usually men who treat women as goddesses, constantly complimenting them on how beautiful and special they are, ignoring every fault. It wouldn't matter if a girl carved a hole in her face, the White Knight would tell her that it is beautiful and she's so smart and cool.
Child molsters and pedophiles tend to be white knights.
