To take a crap in the tank of someone's toilet and not flush afterwards. When the next person flushes your crap comes rushing into the bowl all broken apart. A lot will clog in the top. This is mean.

The act of removing the upper lid to a home toilet. leaving an imense amount of defacation inside. the next customer will go and then flush your shit into the bowl, repeatedly.

My ex left me because I wouldn't compost our trash... so I left her an ECO DECKER. That Prius was my composter.

When you take a crap in the tank of someones toilet instead of the bowl. Most often done to a sworn enemy or to your best friend.
