I've seen a few people running around with this extremely non-descriptive adjective. It seems to be caused by:
- No adjective set.
- Chr between 13 and 16 inclusive.
- Str or con 13 or higher.
- Age between 25 and 60 inclusive.
It's somewhat annoying because "male human" (or "female human") usually matches about half the people in the room, leading to: look 1.'male human', look 2.'male human', look 3.'male human'.... in an attempt to find a way to refer to them.
Perhaps people whose stats don't give them a special adjective could be "unremarkable" or something like that? Since most people set their own adjective, that would make them reasonably unique.
