I’m grumpy and I want the world to know about it

  Why do teenage girls on buses around here insist on singing in that slightly irritating warbly female vocalist in a rap-or-garage-or-whatever track fashion, made all the more irritating by the fact that they’re either quite average and think that they’re good or really bad and produce sounds that offend my ears profoundly? The first time I encountered it I assumed it was some over-excited girls encouraged by inebriation and mutual endorsement, but I’ve encountered it on several occasions now, and have come to the conclusion that it’s acceptable behaviour in one of the numerous groups people seem intent on dividing themselves into.
