The act of reversing the "sync" of a cd to ones itunes library after unconciously adding. Typically accompanied with a: "How the hell did that get in there?!?"
"I put my iTunes on party shuffle and in between Dragonforce and The cars, Paramore and Evanescence made an appearance , so I had to Desync them."

"Lamesauce dude."
