- Shut up
I heard a lot of native speakers saying this phrasal verb with their friends. But what I noticed, though, was that they didn’t mean it literally.
What meaning does it give when it doesn’t mean to **stop talking”?
For this AmE speaker, amongst friends, "shut up" could be used to indicate incredulity with what someone had said. For example:
In this case, I would be indicating surprise that my friend had seen Justin Bieber in the flesh.
