Final answer:
Ben is referring to a recent incident or situation.
Step-by-step explanation:
When Ben says "back there", he is referring to a recent incident or situation. It means that something unusual or unexpected occurred in the past and he is referring to that specific event. For example, if Ben says "Something got crazy back there", he could be talking about a car accident that happened earlier or a wild party that took place. The phrase is used to refer to something that happened in the past and is still fresh in Ben's mind.
