The disease in which a white person tries VERY hard to act like a black racial stereotype. Symptoms can include, avoiding making white friends, saying "Nigga" unironically, trying to speak in a deeper voice, and calling his fellow white people "crackers". This disease affects many children around America, and sadly there is no cure for this deadly disease. Prior to this Urban Dictionary article you are reading now, I could not find a name for this disease. So I named it the "Double J Gaming syndrome" For obvious reasons I do not need to explain.
"Yo man that kid has Double J Gaming Syndrome he's trying so hard to be black!"
