I think it's a call to arms phrase and a battlecry. It means they remember whenever terrible happens to them or their leaders, kinda like the 9/11 phrase "Never Forget". And when something bad happend to the North or it's leaders, they wage war on it. Areys Targaryean killed Ned's father and older brother, so they joined Robert Baratheon in his rebellion. Joffrey killed Ned Stark, they rebelled against the Iron Throne to reclaim their independence. House Bolton betrayed King Robb and sold out the North to the Iron Throne and were their collaborators. So the North rebelled against House Bolton. And now they have their independence once again.
