Answer:
Jack is a jokester in my class, and although I call him this, he wasn't a very funny one. He was an annoying one, at least that's the impression I received from of him. I sat at the front of the class, meanwhile he sat in the back and i could always here commotion coming from his direction. He liked to do impressions of different characters, even hurtful imitations of people in the class. Im lucky my seat is far away from him.
the synonym was "imitations"
