Similar symptoms to being drunk and obnoxious. Sushi brain is a condition caused by eating excessive amounts of sushi in one sitting (especially rolls).

Once sushi brain develops, you speak much louder than you realize, start saying stupid shit, and laugh at things that aren't even remotely funny.
The sushi restaurant had to cut off Devin and Cecil once they got sushi brain after the big order.
