I've not even heard of any of these shows before, but certainly in that first clip in British English it'd be more normal to say "You ain't worth shit". > For sure. In my experience, in the U.S. that use is almost always preceded by "little": Yeah, we often say "little shit" in the UK if we want to emphasis how unimportant we thing they are. That said, I've since thought of some almost counter examples to my original comment. I know "shizzle" derives from "shit", and I have heard "It's the shizzle" before (but again originally from US sources, it became a popular phrase in the UK around the late 90s, but largely disappeared now). Thinking back, I've also heard "It's the m**f**g shit man!" but it was always done in an over-the-top way, also rarely, and usually as a parody. Maybe it's just the intensifier in that. I think "It's good shit" and "It's bad shit" mean the same as without "shit". And I still don't think I've ever just heard "It's the shit" on its own, other than that source you cited and that's from the US not the UK. Even "That's the shit" to me would just mean "this is the stuff" with an implication that there's something wrong with it, maybe illegal, maybe broken, whatever. In the UK, "the shits" also refers to diarrhea, so maybe that's why we don't use "the shit" in a positive sense here. Of course, maybe the younger generation do, and I've just never noticed it.
