Bobby Douglas Burns ,also known as NASTY BOI, is an American YouTuber who is best known for working with the popular channels CinemaSins and Shane Dawson. He never quite fits into a proper category since his content goes through many different phases over time. Significant points were when he did film reviews, where he focused on movies in a more serious manner, genre-mashing trailers to give beloved movies a different feel and video commentaries analyzing YouTube trends.
