Shitberg

TNoun: similar yo how much of an iceberg is hidden below the surface, a shitberg is a person who at first seems only slightly shitty, but once you really get to know them you come realize that the depths of their shittiness knows almost no bounds and stretches far below their surface and can sink emotional ships with ease.

Kenneth Price is a real shitberg. At first he just seemed mildly annoying and a little shitty, but little did I know, the depths of his shittiness were hidden under the surface and unimaginably rich, deep and dark.
