A black person who thinks hes good at battlefield but hes really not. He cares to much about his kills and deaths and not about his teamates. He is really bad at the game but continues to think he is the best. He is bad at any FPS and he should just sell his xbox and switch to wii.

A person who has no eyebrows so he has a nine-inch forehead. He is also so addicted to taming.io that he plays it all day during class, grinds it at home, and would pay his life savings to actually be good at the game (which he isn't).
The Forehead Fairy: The forehead fairy will bless you with his nonexistent taming skills!
