There's this girl that I'm kind of dating and she has this punk bothering her. He posts shit on FaceBook and talks so much shit about her in general. I'm not a violent guy but this makes want to kick some ass. He's pretty much a real life troll and I need to take care of it. Are there any non-violent ways I can get this guy to shut up? P.S. I know this might seem like some underage bullshit but I'm 19 and this pathetic asshole is 20 years old and he's living with his mom and isn't in school or anything.
