Mr Oboogie, what's the 14 refer to? I know 88 is HH, Heil Hitler, but the 14?
It's the "Fourteen words" coined by David Lane a member of the white separatist organisation The Order.
Oddly there are two alternative versions of what the fourteen words actually are:
Most commonly, "We must secure the existence of our people and a future for White Children."
"Because the beauty of the White Aryan woman must not perish from the earth."
The first slogan was inspired by a quotation from Mein Kampf:
"What we must fight for is to safeguard the existence and reproduction of our race and our people, the sustenance of our children and the purity of our blood, the freedom and independence of the fatherland, so that our people may mature for the fulfilment of the mission allotted it by the creator of the universe. Every thought and every idea, every doctrine and all knowledge, must serve this purpose. And everything must be examined from this point of view and used or rejected according to its utility."
Whilst 88 is often said to mean Heil Hitler as you say, it should also be noted that the above quote is 88 words long.
