My Piss Brain was so acute I had a hard time unzipping my pants.

Bad Brain

An individual, usually of the Boomer generation, whose brain is clinically bad, resulting in irregular or bizarre behavior, often causing meaningful harm to those around them, especially in the workplace.

Dude, Karen’s such a bad brain that she literally didn’t know how to right-click. That paired with general cosmic confusion caused her to miss 47 Zoom meetings, because she can't figure out how to enter the meetings.

Tom- Probably cause of that K2 you smoked the other day.
Johnny- I think my brain is messed up dude!
Tom- You have massive Mush-Brain!
Johnny- Fuck Mush-Brain.
