A friend, associate or colleauge that plays one particular or a small number of popular songs repetitively to the point of distraction.
Wes got the new Kings of Leon CD and he plays it right next to me in my cube over and over again. He has played the damn thing four or more times every day for the last two months like an eight year old with a new Raffi DVD. I used to like it, but I hope I never hear it again. He really has the Raffi Syndrome.
