Brain Rot Syndrome

A behavioral phenomenon where an individual frequently uses specific words or phrases that are generally considered bothersome or cringe-inducing. This repetitive use becomes habitual, making it difficult for the person to avoid incorporating these terms into their everyday language.

Leo got hooked on the song “Skibidi” and started saying it all the time. He also used “rizz” to describe people’s charm, even when it didn’t fit the situation. This habit of using “skibidi” and “rizz” too much is what you’d call Brain Rot Syndrome—it’s when someone can’t stop using certain slang words that others find annoying.
