1. Large dog with black and brown coloring. Rottweilers have a reputation of being aggressive and dangerous.
2. A person who is aggressive and mean for no reason. They hold unnecessary grudges and seek "revenge" on innocent people by being cruel, manipulative, deceitful and dishonest. They think they are the authoritative figure in any and every situation and therefore believe that they are in complete control. This leads them to be arrogant, controlling, and hypocritical. A Rottweiler will not let a situation and/or person go until they feel that they have "won". They are selfish, reckless and wild.
The best way to deal with a Rottweiler is to ignore them. Or call him/her fat and ugly.
Person 1: "What kind of dog do you have?"
Person 2: "A Rottweiler."
Girl 1: "Wow, that girl is obnoxious!"
Girl 2: "Yeah, she's a total Rottweiler."
