Too much stuff in too small of an area.

Are you speaking of the black hole of Calcutta?

With so loose a definition, there are things which are not black holes which people could naively take to be black holes, such as my daughter's desktop.

I don't think it's a matter of "too much", just a heck of alot. If one wanted to sum it up so simply, I'd have to define it as "as much stuff as close together as it gets". And when there's that much stuff together, the stuff gets greedy, it wants more, and takes anything else that's around it.

Astronaomically a black howe is an object where the gravitational forces are so great due to the high density of the object that the escape velocity becomes greater than that of light.
