It's not a conventional situation
it shows that using complex words does not necessarily make one's language clearer or more understandable.
If a bully bothered me at school, I would first ignore it. Then if the bullying gets worse, I would ask him/her to stop politely(be patient with bullies they are having a hard time, and thats why they are most likely picking on you). If it doesn't stop I would report it to an adult, or a parent. It will stop after this, if it doesn't then talk to the bullies' parents or the principal
