Well, I picked demigrump for a couple reasons. The grump part is obvious, of course.
I picked demi as in:
Demi-God: Demigod lore is cool, yo.
Demiboy: Sometimes I feel more andro than anything, so if we’re going into the most specific of specifics, demiboy fits me well, but I prefer to just roll with transgender because that term fits me well.
