When speaking of a teacher, specifically your favorite teacher or one who spends his time abraod, in forested areas. Calling a teacher the Duellinator gives him great respect and power, and should be used with only the smartest and best teachers. A great term, only use sparingly.
Student 1: I really like that Geography teacher.
Student 2: Ya girlfriend so do I.
Student 3: Well he is the Duellinator, so everyone will like him.
