On a package of tea I found a sentence as follows:
If you have any questions, feedback or are not satisfied with this product, please contact us at our details below and we can talk tea.
This makes me confused since, as far as I know, talk is basically an intransitive verb and so it isn't followed directly by an object. If an object follows the verb, it should be followed by a preposition like over or through, as in we talked our problems over; but there is no such preposition in my example above.
Oxford Dictionary of English also provides an usage of the verb with no object: used to emphasise the seriousness, importance, or extent of the thing one is discussing. Considering the context of my example that is related to a product to be discussed, this explanation seems to be the one, though the dictionary only lists up examples where the progressive form is used, like We're talking big money.
