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.

backstash 

The act or acting of trying to cut someone off, either verbally or physically. Making someone feel uncomfortable or uneasy while eating a freshly ripened banana. Also see: stashing

I was walking down the street with my friend, when he walked in front of me and cut me off when talking to him, he double backstashed me.

I couldn't enjoy my banana because the turtle was backstashing me.
