Bullying refers to a repeated and systematic mistreatment of others - so a bully would deal with a conflict in a way that is harmful to others. A bully would then go beyond trying to win a conflict, but would also for example verbally (or even physically) abuse the bullied person, or engage in harmful practices such as gossiping, work sabotage and humiliation.
