@Varyag Totally! Be whatever you want.
I was using Gremlin in this general context: https://www.reddit.com/r/OutOfTheLoop/comments/o4alzz/what_is_up_with_people_calling_someone_a_gremlin/
Where people self identify or use it as a term of endearment to mean slightly weird, antisocial, and some combination of cute, diminutive, hungry, and non-threatening
It feels much more prevalent in certain online spaces, like alternative social media
I'd intended my original post as a joke more than any actual self identification
