It's about being disgusting, about following the cultural rules of a society that hardly agrees with itself.
You just received a blast of smell from the strongest orc EVER. That smell consists of everything and everyone he has ever devoured. That is the smell of victory. It is a smell that touts the single rule of life: The strongest eat, and the weakest get eaten. That fart is a truth. It represents everything an orc should want to become.
How the fuck would smelling that shit(there were chunks) not empower you?
Orcs.
Fucking.
Rule.
You just wait for the next orcfest.
