So you know how chimps do social grooming, picking each other clean of the various bugs and parasites that live in their fur? Well, the Gnorsh starts to develop something like that.
Herds of Gnorsh will practice social grooming by way of brown-nosing each other. But this ain't because they have a fart fetish, it's to help remove buttleeches from their herdmate's body. Fewer leeches, the fewer nutrients get lost to b the parasites.
Nasty? Absolutely. But Nature is a practical sort not concerned with little things like propriety or decency.
