In the real-estate world the "asshole" would rent it out to others (such as taxidermist or baker) for cheaper until She'll or BP would show up. I guess in the web world this is equivalent to the trashy ad-filled sites you see on parked sites. Why is it? I guess maybe taxidermist and bakers of the web are cheap and would rather pick another domain. Or is just not possible to legally 'rent' out a domain.
This is the taxidermist and the baker looking at a vacant lot and wishing they could afford to open a shop there, but they can't because some asshole is sitting on it, waiting for Shell or BP to pay over the odds for the land when that won't happen because they can get land on both roads cheaper and put two of their own competing brands up to capture all the gas sales in the area.
