Slop.

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.
