I know very little about hockey.
It's like soccer on ice, but I know very little about soccer. Still, I do know that hockey players are generally perceived as being tough. They're willing to take a hit and just keep on going. They're bloodied and bruised on a regular basis, it's just part of the territory.
So when I say the unsightly and somewhat discolored lump just beneath my knee bone is a hockey injury, it makes me seem pretty tough and not one to be messed with.
Plus, just the fact that I participate in hockey gives me a certain aura of adventure and mettle. And now that it's shorts and capris season, and my injury is noticeable, the fact that it's a hockey injury might make people think twice before messing with me.
"Hockey injury", I think, sounds a lot better than, "konged my leg on the sturdy leg of a table at the library", or more precisely,
I was tutoring a hockey player when I konged my leg on the sturdy leg of a table at the library.
Therefore, it counts as a "hockey injury".
That's my story.
