I do remember having the red orc game over scene by fighting one on the wasteland(near orc tribes). those red orc with their dicks literally hanging around. I fought them with a very low sanity, and I think it's a very low chance, but one of their move(and I think it can only happen if they're turned on already) is the red orc grabbing your head and yeah. but no game over if you just submit to them tho, they really have to do that specific move on you on a battle.
