People who do this at events such as concerts, parties, celebrations etc
RAAAAAAAAHHH!!! IT GETS ON MY NORKS!!!!!!
Why? Why? Why? Its so loud and piercing and obnoxious. I was having a great evening, celebrating my Dad's birthday, at the pub. There was a live folk band (who were really good, for the old farts that they were), and some numpty kept doing the finger whistle1!!!!!
And no, I'm not jealous because I can't do it......not one bit.... well maybe a little, but it was still annoying
