When you find various fine, or tattered, under-bridge denims (or possibly from the sewers), boiling denim is the process of sanitizing them. This works best in a water-filled denim pot on a hotplate. Obviously, you finish them on the radiator.
Charlie was boiling denim again. When is he going to stop foraging under bridges for eggs and denims?
A classic song by Camper Van Beethoven, with (naturally) a somewhat surreal premise, odd lyrics and a funny video, if you can ever get a hold of it.
Also, a classic name for your bowling team, which will provoke innumerable questions from people who don't know what the fuck you're talking about, and praise from those rare folks that do.
"Bolivian Marching Powder" appears in Bright Lights, Big City by Jay McInerney published in 1984. The main character describes the brain and inner soldiers marching around once they've been stimulated with cocaine.
"All might come clear if you could just slip into the bathroom and do a little more Bolivian Marching Powder. Your brain at this moment is composed of brigades of tiny Bolivian soldiers. They are tired and muddy from their long march through the night. There are holes in their boots and they are hungry. They need to be fed. They need the Bolivian Marching Powder." - Bright Lights, Big City, Jay McInerney, 1984
