I would say
There is no justification necessary to label yourself as whatever the **** you please

I label myself as an adorable trap wearing a hairy man suit with the soul of a sentient buttplug from the planet Excelsior

But the trick is
Your self identified label doesnt matter, and is completely irrelevant to your life and everyone elses life

It's purely for self amusement or whatever personal bedrock you need in your personal moments

Like a tattoo on the underside of your nutsack
It just doesnt matter
