Forgotten leak
When you take a long crap, get up, pull up your pants and wash your hands, after, you notice that you have forgotten to take a leak, but you are too lazy to take a one, and leave.
John: Man i just took a dump, and forget to take a leak, but I'm too lazy to go back and take one.
Joe: Damn, the forgotten leak, i hate it.
Joe: Damn, the forgotten leak, i hate it.
