I've always considered "high concept" as an idea that has never been approached, something so outrageous and original it could never be approached again by any other writer. (Well it could, but it would never be as great.)
For instance-you can't write a script about some crazy scientist who brings back dinosaurs without having Jurasic Park come to mind. You can't write a script about a person who sees and talks to dead people without having The Sixth Sense come to mind.
If you can think of a similar film of which your script can be related to, you don't have a high concept. A high concept stands on it's own. It's the film everyone remembers when a specific subject comes to mind.
What movie do you think of when I say "the end of the world". More than likely everyone is going to think of the same movie. That's because that movie stood out, it was the best of it's kind, and it's the one everyone will remember. It had a "high concept".

Eh...not really.
A "high concept" is a story whose premise can be summed up in few words than a full logline. It's usually a bit extreme in expressing the drama and stakes.
But, high concept doesn't necessarily mean that it's unique.
A film that can be summed up by "It's X meets Y," would quite possibly still be high concept if the X and Y films hadn't previously existed.
Die Hard is high concept (terrorists take over an office building).
Steven Seagal's Under Siege is also high concept, yet benefits from Die Hard's previous success. (Under Siege's "high concept" would be, "It's Die Hard on a battleship."
That crappy movie "O" would be "Othello in high school."
High concept also doesn't mean "good." Following the first example, "Executive Decision" or "Passenger 57" could both be described as "Die Hard on a plane," and both were forgettable movies. As well, both Jurassic Park and Carnosaur have a simliar high concept (dinosaurs are brought back to life), yet Carnosaur was a horrible B-flick that I'd like to have wiped from my memory.
As Joe and Dpat have indicated, "high concept" simply means that the story's concept can be EASILY summed very quickly (fewer words than a logline).
"Liar, Liar" is a great example of this: A lawyer who cannot lie.
The high concept is NOT the logline and isn't intended to give the full story, merely the overall, hooky concept.
