Shit hit the ceiling fan

A way to describe how bad things are or will be and the effects will be widespread. Yes, when shit hits the fan its bad and only get on you, but when it hits the ceiling fan it's getting on everyone and everything.

Did you do your part of the homework?
No, dude! Shit hit the ceiling fan and now everything is mess up!
