So around a month ago, my friend started dating this guy. They dated for two weeks and he stayed with her in her dorm. He’s not a student at our school, so she cooked for him, cleaned for him, etc while all he did was live off her. She even loaned him her car. 

So imagine our surprise when she finds out that he cheated on her the whole time with another girl IN HER CAR. They obviously break up, and he starts dating the other girl. The other girl comes outside my friends’ dorm to “collect his stuff” and talk shit about my friend, and it’s all messy. 

Come to find out, this guy is also cheating on the girl he cheated on my friend with. He sleeps with anyone he can sleep with. I personally think he’s the definition of trash but that’s just me. 

So the other day, he comes to my friend’s dorm. He asks her what she’s cooking, and she gives him food (the fact she stills speaks to him appalls me as well, but anyways). He trashes my food and then says hi to me and my friend like we don’t hate him. Then, him and his friend (who I also have a problem with) go into her room. 

My friend and I are in shock, and start discussing it. At first, we whisper, but I wanted to let him know how I feel. I shouted “wow do we really allow trash guys in this dorm” and “no one wants you here, leave” in the hall audibly so that he could hear it. Everyone in the suite could hear me, but it was obviously directed to one person. Him and his friend left, and it’s likely due to what I said. 

While I know I was INCREDIBLY immature, I don’t really regret my actions because I think he’s a piece of shit who doesn’t consider the feelings of others, so why should I consider his feelings? To cheat on multiple women and stick around at this school just to sleep with girls and be dishonest is gross. But, obviously I’m biased. 

I was wondering reddit’s opinion just out of curiosity. 

tl;dr: Guy cheated on my friend in her car and every girl he‘s dated since then. My friend is seeing him again, and I shouted about trash guys loud enough for him to hear, and so he definitely knew it was him. AITA?
