on a message board, a thread where the threadstarter seems like they're sounding serious when it's total sarcasm. this is where people catch feelings and fail to realize it was only a joke.
threadstarter's topic: marijuana has been legalized all around the world (with extensive made-up but believable details)
posters: SAY WORD!!!!!!!!
knowledgable poster: lol it's a shock thread you fucking idiots
