i wanna punch you in the face
Someone who annoys you to the extreme line of near hatred even without doing, saying anything, or even being there that you want to bash them up or you fantasise of bashing them up. In short, the term for a person that you want to punch in the face is called a 'Badger'.
I had a dream of the badger that sits next to me in class, then i woke up and said to myself "i wanna punch you in the face".
