What's left on the ground after a concert. Usually after more hardcore or grindcore and metal concerts, after the mosh, & crowd surfing. Items inlude: Licences, Money, Keys, Broken phone parts, and pretty much everything inbetween. Usually though, it's trash & pointless stuff.
Person 1: "Dude look! I found this 1997 boyscout key chain after that Korn concert on the ground!"

Person 2: "Come on, dude, Put that down, it's just excess concert rubbish."
