Meaning & Usage
"moron, retard, dumbass"
Originally a clinical term for intellectual disability, now a common insult meaning profoundly stupid. 'Sei deficiente?' (are you deficient?) is asked rhetorically when someone does something incomprehensibly dumb. It has more bite than 'cretino' because it implies a fundamental, structural lack of intelligence.
Examples in the Wild
'Ma sei deficiente?' — are you a moron? 'Questo deficiente ha parcheggiato in doppia fila' — this moron double-parked.

Cultural Context
Like many disability-derived insults across languages, 'deficiente' has been fully absorbed into casual usage. Italian sensitivity to ableist language is growing but hasn't yet made this word taboo the way 'retarded' has become in English. It remains one of the most common ways to call someone stupid, especially in Roman dialect.
