An over sized dinosaur-like pig creature. Hippopotami live in African rivers, but also frequent the lush woodlands of Africa. They have a rough, tough outer skin layer that some say resembles the scales of a reptile and many rows of sharp, pointy teeth that they use to eviscerate each other for exclusive rights to rough, rowdy Hippo sex.
Their primary contribution to the environment is taking shits in the river, but the natives of Africa could easily take on this job, making these ugly fuckers basically redundant and useless.
When a person's face is so bloated and deformed that it's impossible to distinguish it from their ass. As it is, the ass already resembles a hippopotamus face. For the poor bastard sporting one of these, it also resembles theirs. It is a synonym with "Ed Zachary Disease".
Yikes - look at that double hippopotamus. If he ate with his ass and sat on his face, I wouldn't know the difference.
