Artistic style; "Grunge" is made by piling up many seperate images and textures. Scratches, splotches, bits of text, grids, and random buildings are all commonly used in this type of art. The end result has a raw, dark look. Tends to be associated with the stereotypical "depressed teenager".
"I just downloaded 38 different grunge brushes for the graphic program of my choice and will now use them all to create a grunge signature."
