smart-alick teacher 

the teachers who think they know something but they dont. and the teachers who think its okay to call a student "self-centered" or immature. well teachers, most of the time YOU are the one being immature and self-centered. teaching is not about being hateful towards your students. if you are going to do that please find a different job

Teacher: "you are so self-centered"
Student: "i dont appreciate being called that"
teacher: "dont tell me how to do my job"
student: (thinks in their head, "youre such a smart-alick teacher.....why do you even teach again?")
