Erf (the name originates from the word "oof") The type of person who always joins a verbal fight, backing up the person he/she likes most. Always insults others and when others insult him/her tells the teacher or person when someone insults them. Acts innocent in front of teachers but acts up when teacher is not there.
He was acting like a real Erf when there was an argument between two people.
