Yeah not absolutely every meme/slang listed might be originated on 4Chan. TLDR seems to have originated or at least popularized by the SomethingAwful forums, which together with ebaumsworld could be considered the parents of 4Chan (with cross-pollination by Newgrounds?). But 4Chan was the crossroads of all these memes coming together, germinating and spreading to every other site shortly after.

1. Yes

2. No.

Deal with it.

It was the r/the_donald exodus and I will fucking die on this hill. I was there. I saw it.

Reddit banned that sub and many of these boomers migrated to /pol/. Trump posting turned from being ironic to legit. You could spot the ever increasing facebook boomer memes and that was also the point where Twitter screenshot posting became the staple of the board. By being pretending to be retarded, /pol/ attracted and amplified actual retards who took over. 2016 is when that board should have been nuked but no one wanted to release the sewage onto other places.

Yooo that’s like, your opinion man. I’ve often encountered some legit amazing stuff there. It really is the place where 80IQ and 120IQ people mingled, with the 120IQ people pretending to be retards and the 80IQ people pretending to be smart.

I don’t know. It’s better here than Reddit which is why I drop by. But I think jannies here get ban happy when I break out the N word to basically say hi or close every statement with a request that the person I’m responding to may please kill themselves. Not the same.

You think wrong. 4chan’s impact on internet culture late 2000s and the entire 2010s can’t be overstated. And that includes getting Trump elected twice.
