Am sure someone out there has tied something similar and given this kind of fly a name but I just call it "The Skoteen" because it looks like a rubbish fly up to no good! 15 mm Olive rabbit zonker tail. then palmered the zonker along the hook shank to the hooks eye. Then added a splash of my "Mushy pea"slab slayer ice dub blend to the front. 35 mm of meaty goodness. I've only caught one Brown Trout so far with this fly but I do like fishing with it, especially on rivers.
