Chongo tells me that these problems arise among apes and monkeys too...as to which word is considered acceptable and which isn't. Some chimps find the word "chimp" itself insulting and insist on the full term "chimpanzee", while others prefer terms like Primate-American, or African-Primate-American. "Knuckle-dragger" is frowned upon by most, while "banana peeler" is looked upon more favorably as long as it isn't preceded by the word "dirty".

Whatever the case....the expression "poop flinger" is definitely considered an extreme pejorative by ALL chimps nowadays, and one should not use the term under ANY circumstances.
