For the uninitiated, I believe the meme comes from Reddit, where there is one criticism subreddit, r/ThatHappened where people accuse other Redditors of making up stories of events that never actually happened, and then a meta-criticism subreddit, r/Nothingeverhapens, where people make fun of r/ThatHappened as conspiracy theorists who think everything posted online is fake. Hard to tell how much of each subreddit is trolling and how much are people earnestly criticizing each other.

It comes from 4chan, like all decent memes
