All South Indian guys are dark 

The first and foremost comment is they thing they are dark. Of course south Indians are dark but not all south Indians are black. Indeed south Indians are not black they are reddish. The temperatures in South India are high when compared to other parts of the country so eventually the skin would become tone to adjust to bare the heat. They have dark eyes and manliness and they carry themselves confidently. 2) They are boring and less partying  Well, the South Indians are well cultured and they do agree that they are little shy comparatively, but yeah here some conditions apply. They are shy only towards girls that too unknown girls. They usually take some time to gel up with newbies. Once they feel comfortable with someone they will be the best time pass for anyone. The culture might be stopping them being more partying but excuse me. Have you been ever been to Bengaluru and Hyderabad which stands top in partying.
