uhhh this question might be kinda gross but is the slur 'pissblood' (used for yellow bloods) canon? because if it is doesnt that imply that all trolls have the same color urine (and the same color as humans at that)?

Unless it’s in a walkaround, I haven’t found instances of ‘pissblood’ being muttered, however, Meenah’s Interfishin confirms even Troll Urine is colored like their blood.
