How it's used
While technically referring to neurological disorders in a medical context, this term is overwhelmingly used as an insult to label someone as irrational, erratic, or mentally unstable. It carries a stronger and more aggressive tone than 黐線, which is often used more casually to describe someone acting silly or making a mistake. Using it to describe a medical condition is rare in casual speech, as people prefer specific medical terms to avoid the derogatory connotation.

Common mistake
Avoid using this to describe someone with an actual mental health condition, as it is highly offensive and stigmatizing. In casual settings, native speakers often prefer 黐線 or 傻嘅 to express frustration with someone's behavior.
