Canceling Positive Characteristics?

J

I'm not understanding this. It seems that people are getting canceled/bullied for having positive attributes. One of my favorite people on Facebook was criticized for being a "try hard" and I've also heard the term "pick me"? I don't get it. I AM a try hard. I'm passionate about what I do. I strive to be better every day and I'm constantly analyzing what I need to do better. Am I misunderstanding these terms or is this super toxic?
