a rybergg
A person who lives to make kids cry. They stand by the door waiting to yell at them. They have no control and use fake guns to look cool.
My history teacher is a rybergg. He screamed at me for not knowing who invented the wheel.
My brother's friend is a rybergg. He yelled at my brother for wearing a hat in class.
My dad's coworker is a rybergg. She fired a blank gun at my dog.
