It’s a police code. Like how 187=homicide. I vaguely recall that it means that a person is crazy, but not crazier enough to be a danger to himself or others. But I’m far from certain on this second point.
Van Halen’s studio is (was?) called 5150, which may have been a coincidental address, but it’s also the origin of the title of the first Van Hagar album.
This is not coincidental. For some reason Ed has a thing for being criminally insane. There are references to “5150” from the studio, the album, a few of his guitars, and even the video for “Hot For Teacher”. But what else would you expect from a guy who names his kid Wolfgang?
Thanks to all who responded, esp. Douglips, who gave me the exact etymology of the term. I heard it in reference to that crazed 19-year old who was killed by fellow passengers after he acted crazy on the plane. A guy said he was 5150 and another passenger said that he must either be a cop or a journalist, as they are the only ones who know what that meant.
That had to do with latitude 54 degrees 40 minutes north (around Vancouver-BC) in a dispute with Canada last century. (At least, it was the last century now, but it won’t be in two weeks.) One of our Canadian dopers can fill you in the details I’m sure.
To add to barbitu8’s post, IIRC some people in the U.S. decided that the U.S. should extend up the west coast to 54º 40’. “Fifty-four forty, or fight” was a rallying cry saying, in effect, “Give us this land or we’ll kill you!”
54[sup]o[/sup] 40’ N is the latitude of the southern border of Alaska, far north of Vancouver BC.
This refers to the resolution of the Oregon Country land dispute in the 1840s.
Originally, Spain (this was before Mexico was independent), Russia, Great Britain (Canada was also not independent) and the United States all claimed the Oregon Country. At the time, it was an ill-defined area in the northwest.
A treaty with Spain limited their claims to land south of 42[sup]o[/sup] N, which is the northern border of California. Similarly, a treaty with Russia limited their claims to the coast north of 54[sup]o[/sup] 40’ N. That left the US and GB to contest the area in the middle.
Along came the election of 1844. Polk campaigned on a platform of territorial expansion, with the slogan “Fifty-four forty or fight” meaning that he would go to war to get the entire Oregon Country. He got elected but settled the dispute by treaty. So instead we picked a fight with Mexico. No doubt that was a better move, considering the relative strengths of the Mexican and British armies and navies. On the other hand, we didn’t have a chance to burn down the Parliament building in Toronto again.
Well, that’s right. It’s been a long time since I read any history about that. Nonetheless, Vancouver, BC comes to mind and I’m virtually certain that that was the line agreed upon as the boundary line between the US & GB.
Vancouver BC wasn’t founded until after the treaty between the US and Great Britain. That settled the border where it is now, the 49th` parallel except that all of Vancouver Island was owned by the British.
The Hudson’s Bay headquarters in the Oregon Country was at Fort Vancouver, which is now known as Vancouver, Washington. After the treaty, they moved their HQ to the Frasier River and called the new place Vancouver as well.
