This isn't slang or an idiom -- it just means to drink a cup of tea, nothing deep or thoughtful about it really.
There is no such English phrase as "tea of a cup." You either have a cup of tea, or you have tea in a cup.
'Cup' is a noun in the phrase "cup of tea." It is the object of the preposition 'of' and refers to the container holding the tea.
