sticker [boogers]
The gummy residue left on CD cases, etc. when a pricing sticker, etc. is removed from said CD case. Sticker boogers present themselves when the residue is attempted to be further removed via a hard push with a finger or thumb; therefore balling the residue into a sticker booger
After trying to remove the stickers from his new CD he ended up with a bunch of sticker boogers instead of the pristine CD case he'd hoped for.
