I'm gonna pretend you want a real answer:

Most of the folks I've met who are post leftists or green anarchists or nihilists are folks who got burnt out doing conventional organizing in the Iraq War and OWS era. Their rhetoric is definitely more inflammatory than what they actually do, which is a lot of activist scale organizing with immediate tangible results (like picketing a wage thief or distributing aquired food and warm weather gear), as well as participation in demonstration and leading by example.

The big difference is that they don't do party building or union organizing or non profit work, which is what they usually mean by "post left" but they'd certainly participate in anything we'd recognize as a revolution.

So in short, it's a response to the difficulty of activism akin to someone after a breakup "working on themselves" and hooking up with people instead of looking for a long term thing.
