sticker poop
the tacky residue left behind after removing a sticker or price tag from an item, often causing a black sticky film to build up on the object.
1. i tried to remove the price tag sticker from the glass of the picture frame carefully but couldn't so now i have to look at the picture through all this sticker poop.
2. i removed the sticker lable from the cream bottle but there's all this sticker poop on it.
