Fourteen Words is a slogan commonly used by white supremacists. The slogan usually states: "We must secure the existence of our people and a future for white children." The slogan was coined by a white supremacist, David Lane, who died in prison.
Sometimes the slogan can be stated as, "Because the beauty of the White Aryan woman must not perish from the earth." And some people merely refer to it as 14. Or 14/88. 88 refers to the 8th letter of the alphabet (H), thus it stands for HH, which, in turn, stands for Heil Hitler.
