There should be a word for this.

The sudden urge to overcorrect, overexplain, or behave unnaturally when trying to hide something, often making the very thing you're hiding more obvious.

The phenomenon of a pet being called a dozen silly nicknames until it does something wrong, at which point its real name is deployed with full legal authority.

The insistence on staying awake a little longer even when exhausted, as though sleep were a deadline you can negotiate with.

A word you know you know that hides in the back of your brain and refuses to come out when needed.

The elaborate follow-up message correcting a typo that was perfectly understandable anyway.

The euphoria of finding a parking spot exactly where you needed it, a joy wildly disproportionate to its significance.

The polite chewing-and-smiling expression deployed while eating something terrible that someone has proudly served you.

The unstoppable laughter that erupts at precisely the moment laughter is forbidden.

Cleaning everything except the thing you are actually supposed to be doing.

The mental treadmill of replaying a finished conversation, searching for the thing you should have said.

The fear of listening to a voicemail, on the theory that it contains either bad news or a person you'd rather not speak to.

The paralysis of being added to a group chat in which everyone else already knows each other and is speaking in references.
