ip in every-day language

In an article about the post-Brokeback cowboy fashion revival [NYT 2006/3/9], I noticed this paragraph:

When you unravel the history of cowboys and their clothes, the 150-year tug of war over who’s a cowboy and who’s a dude, as department-store cowboys are still derisively called, gets tangled. The Wild West may be the place where branding was born, but if the last 150 years have made anything clear, it is that no one has staked a clear copyright claim on cowboy style.

I’m not sure what it says about our culture that IP concepts are simultaneously so ubiquitous and so mangled.
