I'm yet to find it. For a meme-ish sub /r/wallstreetbets is pretty good. Go there and have a laugh. But places like /r/economics and /r/finance are utter shit.
The best resource is financial twitter (fintwit). The news breaks there, the discussion happens there, and loads of meme-ing also takes place (which is always a nice to-have in a serious place). The only drawback is that most of them lean exactly the way I do. So I can bear the place, but I miss out on a bunch of opposing opinions and it's always a challenge finding someone on the opposite side of the fence.
