I do not see a issue with it lol, I've never actually used "Bae" or "Lit" but I do use FAM a lot but honestly I don't even see a issue with any of the sorts of slang

I feel that's it is only annoying simply because there is absolutely no need for them to say it. Some people go out of their way to say these weird slang words that most people don't know the meaning of. They then have to waste more time explaining what they mean, when they could have just used the proper terminology.
