Jello Brain

Brain fog the day after a night of excessive drinking. You move a little slower, the brain doesn't function like normal, and the simplest of tasks take 3 times as long.

I can't remember the name of that song, I have Jello Brain today.

Oh Jello Brain got lost on the way over, he stayed out until 4 am.
