It's when you go and clean up a mess, then you turn your back for one second and it seems like two more, or the original sized mess has now doubled. Because people around you don't have a basic human functioning such as cleaning up after themselves, Or they are too lazy to do so.
( I swear to God it seems like I am living in a crack house, Or a horders. And at this point in time I can't tell the difference)
"Cleaning up after this hydra mess is going to be the death of me. It seems like I turn my back for one second and two more have sprung up."
