The phrase exists in English too, "to shit on something". It means to talk bad about something, to criticize, to make it (or someone) look bad. I think "shit" in English is one of the most linguistically flexible words, used in various ways, from very positive ("It's the shit!") to negative ("It's shit") meanings. As another commenter said, the positive meaning of "shit" often seems to be the result of reversing a common phrase. "I don't give a shit" means I don't care at all, not even a shit; and later the opposite phrase started to be used, "I give a shit" to mean I do care about it. It's one of many confusing and illogical things about English.
