When you have one or more stickers that you love so much, that you can't bring yourself to put anywhere in fear that you will waste your stickers.
Ashley: Josh, I really love that Hello Kitty sticker book with over 100 stickers you got me, but Now I have no idea where to put them. You can't just waste stickers that cute!
Josh: They're stickers....you have over 100 of them....put them anywhere and everywhere.
Ashley: I can't! I have sticker anxiety!
