The term "brain rot" refers to mental fatigue or reduced attention span caused by consuming large amounts of low-quality, repetitive, or highly addictive online content. The structure is a metaphor where "rot" implies deterioration, used hyperbolically to describe cognitive overload rather than literal damage. It is informal internet slang commonly used to criticize or joke about excessive scrolling, memes, or short-form media consumption.
