Green humor

A type of humor characterised by its exclusionary nature. The punchline of a green humor joke is that you have a vague idea of what it might be about, but the specifics of it are incomprehensible and impossible to decipher. A good green humor joke is incomprehensible to even the teller of the joke. You can find this type of humor on r/coaxedintoasnafu or r/smugideologyman.

Victim of "Joke": "Wait, what's the punchline here? It sounds vaguely political, but what does this have to do with anything?"
