Nick Diener of punk band the Swellers played Miss Manners and offered etiquette tips during their most recent tour.
From now on, I'm going to apply the term "doff" to whenever I remove my headphones to talk to someone.
Example: "So I was walking down the street the other day when I ran into Hank so I doffed my headphones and went 'Dude! Have you heard the new Death Grips single yet? It's raw as hell' and then I kept walking because it wasn't actually Hank and I felt embarrassed."
