Everything should be explained in there. I may have posted this on another account but I don't care I can't find it so here this is. It's weirdly fun to try to pronounce these. This will generate (mostly) pronouncable letter combinations that you can use however you want.
All code by me DISCLAIMER!! There is a chance that this could generate swear words or other profane language. This is not an intentional thing and is unfortunately part of the way the generator works. There is a filter in place but it is imperfect. For this reason, it's probably best if you don't try to read them out loud (even though it's pretty fun to try) until you've confirmed that they don't sound like swear words. Unless you don't have a problem with swearing, which is your choice.
