soiface is the original quirk chungus. "haha look how wacky i am and the ridiculous face i'm making because i just don't care if i look silly, that means i'm actually very masculine and confident!". however it's obviously a fear grimace and not a sign of masculinity but the opposite.  the female form of it is quite similar, but in a "look how easygoing and fun i am!" but also means the opposite in reality; she will make your life a living hell.
