Some one who will shank a bitch, ho, motherfucker, or anyone in any way inferior. Usually the shankapotomus travels in teams and can be found in the woods of Germany writing and illustrating children's books. Don't interrupt it. Or it will strike. The shankapotomus is a known diva and badass.
Yo, better watch out I hear the shankapotomus is in town. It will fuck your shit up, bro.
