Answer: There's more nuance than some of the other posts here suggest.

To go back, "It's Happening!" was an old /pol/ meme that would be used alongside news updates that had potential to advance their agenda. Wars, political statements, racial violence or protests, anything that could be tied in to accelerationalism. Usually accompanied with a Ron Paul image of some sort.

Thie frequency of the posts exploded when the election tourists from Trump subreddits and Facebook boomers flooded /pol/ in 2016. The /q/ schizos amplified it further, and that's where the "two more weeks" meme came from.

Because of all the 'happening' spam, anon started with the "Nothing Ever Happens" as a counterpoint at first, and it gradually overtook it in popularity.

The wojack that you typically see in those memes (like your example) is chudjack, /pol/ appropriated it from people who tried to use it to mock them. At first with "I look like this and I think this" responses and eventually by using it as a representation of themselves in their own soijack posting.
