We love our mods, don’t we folks?
I didn’t think it had anything to do with what you just said. I remember it being a meme that started on Reddit as a way of calling someone a rightwing person who is making stuff up. Both “post hog” and “hogout or logout”.
The founding incident happened when users baited a rightwing user by demanding they post pictures of their penis as evidence in a ‘pics or it didn’t happen’ situation. With the chapo subreddit and so many other left-wing subreddits now removed from Reddit, sadly I can’t find the original thread anymore.
The version I heard was a chud wandered in on the same account they posted to nsfw subs in. People noticed this and and started roasting the guy. His defense was that “it was a bad photo”. He eventually got mad and posted more.
I think Awoo is right in terms of memetic etymology or whatever tracing the origin of a meme is called.
