Treebeater 

Treebeater is a racist and derogatory term used in a similar way to "n*gger." It usually is referring to a stupid African American person. The origin of the word came from a Reddit post about a special species of Chimpanzee that communicated via beating trees. This was quickly converted into a racist joke that compared the monkeys to black people

Terrell: "Hey Luke, go somewhere else. Racism isn't cool."
Luke: "Terrell shut the fuck up you fucking Treebeater, go back to my fucking cotton field and beat a tree.
