THROW UP = VOMITAR!!!
I think phrasal verbs were invented to make sure that English teachers have a job for life! So, we should all be very grateful to phrasal verbs because they make sure that English teachers have the same job security as "funcionarios"! jaja.
"Throw up" is one of those interesting ones where you need to be a little bit careful because it is very easy to say without really knowing what it means. Thrown in, Throw out, Throw through, Throw off, Throw at, Throw to, Throw over are other examples of phrasal verbs with "throw".
If you are able to make a sentence with each of those, you are ready for the Advanced Cambridge exam!
Hope that helps!
