While in high school a friend's boyfriend was super jealous of me around her for no good reason, with that in mind I made sure to always hug her longer, greet her with a kiss and say how beautiful she was just to get under his skin, one day the bf was by himself and I asked about her just to fuck with him, worked like a charm as he went nuts and tried to KO me, being a thai boxer and much taller I avoided the punches and laugh. My buddy who knew what I was doing descalated the "fight" and told me to stop being a cunt. At that moment I realized that the bf behavior towards me didnt excuse my actions, even though the guy really was a POS as we got into a brawl months later.
