This might be a little bit meta, but nobody’s mentioned it yet, so it has to be said:
Potheads.
The distinction here is that very few potheads sit around and smoke weed — and then do absolutely nothing. No, they smoke weed, and then they engage in various activities: many of them hobbies that have been mentioned in this thread. And the infusion of marijuana into the activity makes the already tedious wankery even more tedious because it’s filtered through the single note of potheadedness.
Foodie pothead: “Yeah, but have you ever tasted foie gras… on weed? There’s like this whole other layer of texture, and the flavor has so much more depth, you can like taste the grain the duck ate, and…”
Sports pothead: “Yeah, but have you ever watched baseball… on weed? You can actually see the pitcher and the batter trying to read each others’ minds, man…”
Cinemaphile pothead: “Yeah, but have you ever watched Bad Santa… on weed? It’s just so dark and so mean, it’s amazing the movie ever got made, it’s like the producers had no idea what kind of movie they were signing off on…”
Gamer pothead: “Yeah, but have you ever played HALO… on weed?”
Audiophile pothead: “Yeah, but have you ever listened to Miles Davis… on weed?”
And so on. I’ve never talked to a stamp-collecting pothead, but I imagine the experience would be similar: “Have you ever compared a mid-1930s British stamp with a late-1960s British stamp… on weed?” or whatever.
Ditto any other hobby mentioned so far, with the exception of those that require intense physical activity. Basically, you take anyone who engages in a primarily sedentary activity, and add marijuana, and you get a hobbyist who is even more obsessive about it than the non-pothead, and who is even more desperate to share the wonder of it all with anyone who will listen.
I win.
