When you try to remove a sticker from something, often a price sticker on a DVD/Videogame etc. and after removing it the glue remains on it, leaving a permanent mark on the good which is almost impossible to get rid of, and making the whole thing look cheap and tacky.
When I tried to remove the price sticker off of my new DVD it left a huge sticker scar! It was so ugly that i had to switch the boxes.
