It's a guy singing that he is the kind of guy that cheats on girls and the kind of guy that girls really hate and the kind of guy that makes them angry and stuff. Basically it means "yeah I'm a jerk but the girls love me and hate me anyway"
chorus" this world is weird because if the guy aint bad they girls wont love him. a guy has to be handsome but at the same time caring and sensitive, that kind f guy doesnt exist anymore..."
