maybe a stupid question but i cannot find it anywhere..

subetarians ?

thanks in advance :)

you know, I'm not terribly sure! Subetians is my guess!

subetans

source: the subetapedia

thank you guys! :D

The common consensus is subetans ^^

this subetapedia article is one of the one that uses the word but I'm sure there are probably other places that reference this as well :)
