Its a way of combining multiple exposures to get a more detailed/better exposed/ more evenly exposed scene (by increasing the dynamic range of the picture, the light 'levels' within, by compressing them together)
Best example would be a seaside view where if you expose for the sky, the foreground will be underexposed (to dark) and if you expose for the foreground the sky will be overexposed (blown highlights etc). Combining 2 or 3 different exposures gives a nice evenly exposed picture.
However the technique can be pushed to extremes and gives some very cool/strange effects. e.g. one of my 'HDR's of brighton pier
