Try paying attention to how a teenage person unconsciously mimics small components of the behavior of a parent or a person they (again, possibly unconsciously) consider of importance. Things like a bad habit, such as smoking (including the finer mechanical details of the process); accent/[mis]pronunciations; usage of idiomatic words or phrases; motions when driving a car; etc. tend to look/sound extremely natural.
