Having a consistent reputation of not giving a fuck and getting in fights one day your attitude gets met with a random guy who's the boyfriend of a girl you pissed off

After a while of pointless insults it leads to you grinning looking up at the random guy on my knees after being pushed whilst he spews insults at me and pulls my hair tightly as I lightly laugh

That's until Mattheo a boy you've never talked to before falls upon the scene... what would this stranger do?
