An autistic grown nigger who thinks he's a dinosaur. This type of nigger is not your typical nigger. In fact, he is one of the most dangerous niggers. If you have watermelons, fried chicken or anything that seems valuable to a nigger, you better hope that you can outrun the nigger.
White person: That niggersaur went up to me and screamed, then stole my KFC.
Cop: Damn niggersaurs... We'll see if we can catch him.
When a fried-chicken loving, watermelon ass nigger runs into your house and inserts his BBC inside of you and then ejaculates a fuck ton of cum into you and/or your children and wife, then he proceeds too steal all of your shit and then run away from the white cops that automatically shoot at him even though they don't know if he has done anything.
