That's Racist is a meme that's really popular and it's also popular with the guys in the Khan Academy Wiki world. You can see the moving gif to the right here. It shows a black boy with a basketball, watermelon, fried chicken and a giant necklace. These are all things stereotyped to be associated with persons of the black race. There are are other variations of the meme like the Jewish, Hispanic and Asian versions. In the KAOS chat room, this meme can be called up by typing (racist) or (that's racist). AJ and TJ like to use this meme, alot, but everyone uses it.
