stupid kid!!!

omgggg I cant believe I'm doing this rn because I don't really rant  but I have to like its this kid at my school and he's a total ass like he's the type of person to remind the teacher about homework I cant even believe he's popular like what and he tried to fight me because he talked Abt my father and lied on me saying that I slept with my ex while I'm dating another person  so I said I can play golf on his eyebrows  and that he can go to hell and I walked away then he punched me so I kicked to the ground and broke his nose and now he's crying am I the bad guy in the situation?
