A form of brainrot that comes from practicing extremely difficult pieces of music, such as Maurice Ravel's Scarbo, one of the hardest piano pieces in existence. Two common signs of this include frequently saying the name of the piece(s) and heavy mental preoccupation with them.
Person 1: What the actual Scarbo is this?
Person 2: You, sir, have scarborot. You're actually so addicted to Scarbo.
