Someone who hangs around you for too long and never goes away.
Quit hanging around me and go home, your such a shit sticker.
After whiping your ass after a massive shit, you throw the shit stained toilet paper straight up, hitting the ceiling. It will cling to the ceiling for a while depending on the binding power of your poo. You can also toss make shit stickers on the stall wall as well.
I went in to use the bathroom at the truck stop, and a shit sticker fell on my head!
