A term one uses when they can't remember anything and are just overall feeling awfully stupid today. When you are trying to solve a math problem, but you completely forget what to do.
Girl #1: Uggh this math homework is giving me a headache.
Girl #2: It's not that hard, we just learned this all in class today.
Girl #1: Yeah, but right now I'm having the biggest brain fart.

Get the Big Brainmug. Gonzo brain is when a persons mind veers dangerously off track; like losing their train of thought, where the one subjected to gonzo brain cannot formulate any real tangible and communicable ideas, and sometimes is left with feelings of impending doom. An occurrence that is more prevalent when subjected to brain injury, mental illness, or the use of psychedelic drugs.
I remember babbling to Tyson about something last night, then right in the middle of talking I got gonzo brain and could barely speak the rest of the night; I was left with this eerie feeling of awkwardness and didn't know what to do with my self.
