I know there is a meme around "lewd" which I believe comes from manga dialogue describing hand-holding and other mild intimacy, for example, as being "lewd." It's sort of an ironic thing. "Newd" makes me think it could be a play on that, but I have also never seen it before. It could be like "noods" or "nudz" which are just intentional misspellings for no real purpose.  I will say I was never one who believed I would always be able to keep-up with the new memes as I got older. I am very comfortable in the fact that Newspeak among the youngins no longer makes sense to me and that that means I'm old now. May my youth rest in rage comics.
