How to deal with extremely insecure small men?

This is really something I have to deal with at school and it really creeps me out. I am 18 and a girl. <br><br>I am pretty tall for a girl - 5 ft 11 - and I often get mistaken for a model. I am pretty skinny and have long legs. I am not bragging, just pointing out why these guys are so insecure. I am not doing anything wrong and I don’t even talk to them.<br><br>These small guys often approach me and just talk and laugh to their friends and intentionally embarrass me loudly. I have had guys pull my hair or bluff at me and push their friends around me and bully them for no reason other than being tall. Many guys just straight up mock how I look and literally laugh at me and make fun of my height with their buddies nearby. <br><br>It is creepy because I am just minding my own business and have nothing to do with them. Is this normal? What is up with these men? Where do I even start to address this?
