When it's the middle of the day, and you realize you have a lot to do and not enough time to do it. As a result, your mind locks up and you can't work, you just sit and pity yourself.
Usually caused by procrastination.
When you procrastinate too much and end up having multiple huge assignments (which you haven't started) due the next day, you may have a mid-day crisis, and end up laying on your bed throwing a tennis ball at the wall. Eventually you either say "fuck it" and don't do the assignments, or you get off your ass and work on them all night.
A much needed mid-day wipe of one's anus after a previous night of heavy boozing/drinking wine/beer, followed by a morning of greasy, wet farts that have the possibility of leaving a brown shit smear on one's undies if left unchecked.
Parker and Hamilton stayed up all night drinking Big Bear 40 oz malt liquors and jugs of cheap wine.
The next day, Parker was having trouble at work. He had a case of mud butt diarrhea followed by a series of beer farts.
He excused himself right before lunch and went to the bathroom for a mid-day wipe.
You started out your day all pumped-up to accomplish the list of to-dos but the obstacles you face along the way overwhelm you by mid-day that you feel lost and demotivated to carry on.
Common cause: bureaucracy.
Perhaps casual chatting with colleagues in the pantry over a cup of tea for a good fifteen minutes will soothe the mid-day crisis symptoms.
