IRL

IRL is a very open label, which anyone who identifies as literally someone or something in real life can use.
It is most commonly found in alterhuman circles, but not exclusive to them.
"IRL" can be used by otherkin, fictives, otherlinkers, and more, or used as a stand-alone term.
The definition of "IRL" is rather simple:
"I am ... IRL."
The person literally is what they say to be in real life.
