German Tree Frog - When someone, without invitation or warning, jumps on your back, thinking it’s all fun and games, pretending to be your friend, meanwhile disposing feces on your back (Typically solid; see also dropping a South Dakota Speckled Beef Log).
Party cancelled due to sanitary concerns. Some stupid kid pulled a German tree frog on his little sister in the ball pit.
