New username

How do people "invent" new usernames!??!
I'm so uncreative, i went by the same username for like 6 years before i changed it to the current one which I've also been using for 2 or 3 years by now.

Now i want to change it and I'm sooo lost. I'm letting chat gpt create names for me. But nothing is particularly good. I really need to change it tho cause irl friends know this alias and I'm redirecting them to mggo all the time and i really don't want them to know it's me.

How do y'all do it?
