Depends on the context. My "real-life" profile is just my firstname + lastname, like many others. This particular username came into life because it was auto-generated when signing up to reddit, where I wanted to post a 3D simulation/physics render I did, so that's what stuck. Then I started using the same user across platforms and brought the username with me.
