As far as flies for salmon go, this one isn't too tricky to tackle. The fly is designed by Barry Thornton and tied specifically for fishing Vancouver Island's Black Creek area.
The tricky part is getting the polar bear hair. As a substitute for the bear hair, saltwater Yak hair is great and has a nice translucent look. Bucktail or synthetic hair will also work. I've used the pink baby bug back from Fly Tyers Dungeon in place of the Laser Wrap, but you could also use Edge Brite.
I'm not sure what the origin of the pattern name is, but it sounds like there may have been an angry wife.
The original pattern is tied with a pink hair tail and wing (might be mixed with some white). It's a recommended pattern for beach fishing in late Agust into October for both pink and coho salmon.
