Short for 'Proggressive rock'. A kind of music, usually typified by very long songs with complex structures and time signatures. It started with bands like Pink Floyd, King Crimson, Yes, etc, and bands like Dream Theatre, Opeth, The Mars Volta and Tool all have strong prog influences, making the old prog stereotype of a middle-aged bearded man in a wizard outfit tediously wanking off his guitar pretty much redundant.
Muse are better in their proggier moments...
