Basically a little while back someone on leftypol made a wojak edit to make fun of people who go on pol for looking the exact same, which is the pic I posted. It remained a pretty small in-joke on leftypol and other leftist spaces, but finally a few days ago it started to really catch on after some people started actually posting it on pol, essentially creating a feedback loop of /pol/ seething at the meme then more poljack edits being made in return. They're literally posting pictures of their chin to prove they aren't chinless lmfao
