What is Apeshit-crazy?
1.
The kind of anxiety usually expressed by the physical or mental desire to jump up and down, screaming and banging hands on chest or head on walls.
Pre-dates the shortened but now more common variant "apeshit."
My roommate just deposited my mail at the bank and dropped my bank-deposit in the post-office box, for the third time! I'm going apeshit-crazy!
