The headline for this story is peak 2017.
Last Wednesday, a Reddit user named /u/HanAssholeSolo posted a GIF titled "Trump takes down fake news (Colorized, 2017)" to Reddit's largest pro-Trump subreddit, /r/The_Donald.
The post gained a few thousand upvotes and, according to Reddit's publicly available metrics, wasn't even in the top 20 of the most popular posts on /r/The_Donald in the last week.
Reddit users started freaking out, and quickly set up a celebration post under the header "Congratulations to /u/HanAssholeSolo. Their dank WWE meme got TWEETED by the PRESIDENT of the United States, creating a shockwave of SJW 'REEEEEEEs' heard all the way from North Korea. You win the unofficial community MVP (most valuable pede) award. Also, now it's confirmed that Trump sees our memes."
There have been rumors circulating on Reddit since before the inauguration that members of Trump's inner circle are active on Reddit and feed the president memes and in-jokes for his tweets and speeches.
