I need some help on an attitude issue i have?

im a17 year old male im quite built. people i know and people i meet always tend to tease me and stuff.its really annoying.when they tease me i m like laugh with them 2 and i dont say anything.but ocasionaly i the past i went out of control and i did dangerous things to people who were too annoying. i have 130 iq so im not stupid ...i dont get why people tend to tease me i just prefer not to be teased at all and be equal with everyone else? sometimes i think of standing up for my self with a little tease but i think to myself''why should i start a fight its not worth it '' and lke that it all builds up in the end.......anybody have any tips to give me?
