What does your classmate mean when he calls you a baboon:

First of all, you must understand that a baboon is a large animal, which is a type of monkey.

Your classmates gave you this nickname. Maybe it's because your figure is more flexible and your classmates gave you nicknames based on your appearance.

For such nicknames to be disrespectful, you can protest against them or explain the situation to the teacher and ask the teacher to help stop this behavior and the psychological harm it causes to you. In addition, let the teacher tell the students that it is impolite to give classmates nicknames.

You should also pay attention to this behavior yourself and cannot give nicknames to classmates.
