The blasé or uninformed approach a touring musician might take with regard to their upcoming itinerary; i.e. a band member not knowing which gig they are playing from one day to the next.
Fan: "where are you playing tomorrow?"
Band member: "Umm.... don't know."
Fan: "Dude that's so gignorant."
Classic examples include Spinal Tap's appearance on 'The Simpsons', where the name of the town is gaff-taped to the back of guitars to remind the artist.
