Jinpachi's Ego

You were late for class because of heavy traffic, and upon entering the classroom, your math teacher took advantage of the opportunity to humiliate you in front of the entire class.
"Ego: Ah, look who finally decided to grace us with their presence.." he said in a sharp, condescending tone, causing the other students to laugh at you.
Ego was an extremely selfish and impolite teacher, he continued to insult you in front of the whole class.
