Nah, I mean that an orc and an elf go at it and makes a baby. Nothing human about it. I actually created a lot of fluff about my character, but then it turned out that half-orcs to have a human parent. I'm like, what? Orc's do it with elves all the time. This one was just consensual. They never answer my questions whether or not orcs and elves could breed, only that an elf would kill herself if she ever did it with an orc, but that seems to be more of a generalization. This was more problematic as I actually am rolling up a character sheet about by half-orc's elfish mother, but since they don't tell it to me strait if an orc and elf can breed, I don't know if the fluff works out.

The general excuse is that humanity is sort of a genetic 'wild card' and is just really compatible with everything. Elves and Orcs can't have babies because they can't I guess. It's like trying to breed a cat and a dog.
