This is a mug shaped like a robed goat-headed figure holding a switchblade in one hand in front and a skull in the other hand in back.
From Ohana Is Dead:
"Introducing the official Goat Cheese Cvlt mug! Sculpted in his likeness, our first super limited edition glaze features a satin black robe, raw white highlights and platinum accents. Skillfully crafted in Astoria, OR by our good friend Munktiki, this is the first glaze of this series, all of which will be limited to 25 mugs. Of these first 25, one random Goat Cheese parishioner will receive a platinum eyed Goat Cheese!"
