Don't be bullied

HOW TO HANDLE A BULLY
(AskMen.com)

Understand the bully: In reality, a bully has a very poor self-image and a total lack of people skills. The bully's attempt to control or overpower people stems from his fear of being insignificant, while his know-it-all behavior has its roots in his dread of being wrong. To combat his own self-esteem issues, a bully usually treats people offhandedly, disrespectfully and dismissively.
Stand up to the bully: It is important to be assertive the moment you sense a bully infringing on you; however, while this early stand may prevent escalation, it may also result in you getting your ass kicked. Generally, a bully has a "baiting" period at the onset of his reign, to see who is susceptible to bullying. If you don't show any signs of weakness, he'll realize that you're not susceptible and will eventually retreat to find somebody else to torment. This early assertiveness needn't be physical -- just speak with authority and confidence to demonstrate a commanding presence.
Laugh off the bully: Although it takes great guts to laugh off the hulking bully who stands before you, it is a surprisingly effective technique. You must understand that there are two ways to use laughter: You can either choose to laugh with the bully, which will position you as a harmless guy not worthy of pursuit, or you can laugh at the bully, effectively calling his bluff and humiliating him publicly. However, if not done convincingly, the latter option could result in your rear getting kicked -- again.
Distract the bully: Distracting the bully will buy you more time and temporarily deflect his attention from you. They say attack is the best form of defense, so defend yourself by attacking somebody else. Before your gym-going competitor can brag about his max lift versus yours, for instance, bring the bully's attention to the scrawnier guy across the room. If this scrawny guy looks weaker and frailer than you, then you can be guaranteed that the bully will have something to say about him and hopefully, in the process, he'll forget about you.
Attack the bully: If actions speak louder than words, then you must attack the bully directly. Study him to find out where his weaknesses are and, the next time he approaches you, rip into his insecurities. If you know that the bullying soccer dad's weakness is losing, for example, constantly remind him of the time his son lost an important game two years ago. His son may well have won every game since, but you can bet that his son's one failure remains very fresh in the bully's mind. However, be prepared for the consequences if you push that "Do Not Touch" red button one too many times.
