First I'll paste a comment I left about this recently:

Yes, but the people who are using it that way are doing it as a cover so they can just cosplay lynching a black person. I'm not saying you are doing that at all, but that is the crowed you end up associating with as a result of using it. There's a reason it sounds like the N-word with a hard R. I've seen enough shit on the internet surrounding the term to know that they are just black-coding all the "robots" in all these conversations/videos. Taylor Lorenz, for as much of a liberal she can be at times, has good coverage of this: https://www.youtube.com/watch?v=nBtbkOfUlIo. Another term that had been floating around was "wireback" which is just replacing "wet" with "wire" in the traditional slur against Mexicans.

Second, Chud and Hog do not root themselves in an actual slur in the same way that "clanker" and "wireback" do, which I always thought was pretty obvious.
