Big Man Syndrome (BMS) is when you are a bigger person and you feel the need to overpower a situation just because you are a big person. It can happen in someone that is fat or someone that is muscular, most commonly found in muscular people.
Someone hits the pingpong ball over the net really high and you know you can easily score but you hit it as hard as you can just because you have Big Man Syndrome.
