If that sort of thing entertains you, you should check out Time Bandits (it's from Apple TV originally I think but can be found on the high seas no drama), and one of the story threads deals with a girl of early secondary school age, left in a prehistoric time - and she ascends to being a leader, educating her tribe with her 2020's saaarh laaahndan banter.

When they head back to find her, the tribe are all conversing like a mob of youths outside a McDonald's on a Saturday afternoon. It's absolutely brilliantly written and well worth a watch.
