backflush 

The turds/toilet paper that always manage to scoot back into the toilet bowl at the end of a flush.

I had to flush the toilet 2 times at work today because of the damn backflush.

karmic backlash

When things go smoothly for a period of time and you're enjoying life, karma finds its way back to you and fucks things up.

I had the best November but I'm getting karmic backlash and December is turning out to be such a drag.

study backlash 

That headache you get after the exam when you suddenly stop cramming and your brain just melts to mush.

I had study backlash after cramming at the last minute for my sex ed test.
I got all the answers wrong anyway, making all that cramming a huge waste of time.
