Not to be confused with being academically "smart", this slang term refers to when a child has successfully figured out the behavioral requirements to get more screen time from parents, which may not
necessarily be uniform from one pair of parents to next. For example, a toddler with an IQ of "only" 78 is already allowed by his parents to be on the iPad for hours on end. Whereas, a 20-year old
college student is "only" allowed to watch YouTube for 1~2 hours per day just because he cannot afford moving out from parents' house yet.
