The medical condition in which a black person turns from a black person to a white person. Some symptoms may include the lightening of hair and skin tone, the shrinking of lips, losing the urge to eat fried chicken and watermelon, listening to more crappy pop music like Justin Bieber or Taylor Swift, the increase in the pitch of their voice, and their inability to rap as well. It is often contracted from being exposed white people for an extended period of time.
