Is OTHER wrong in the post ? POST : Ok some background first:
In my school I have a group of friends I usually hang out with. Last year a kid (whom I'll call Jerry) joined the class. For most of that year myself and my friends never really talked to him. Then eventually we felt bad because he didn't really have no other friends. So, we decide to kind of add Jerry to the group. He seems happy enough and things were going fine until I added him to our group chat. That's when all hell broke loose. First, we had to add him to a separate one because one of my friends (whom I'll call Kat) HATED him. Whenever Jerry and her were together she would just not be for it. So, after Jerry and Kat are separate group chats we realized that Jerry cannot take a joke for his life. So, we have to be literal with everything that we say (which is hard because we all are sarcastic). Once again, it wasn't much of a big deal until Jerry says one day (when for some reason he and Kat were in the same chat) "Hey Kat I like your ass." We were all shocked because he was still new and stuff. Of course we all take offense to this because we've known Kat for longer and we thought he was serious. Then my other friend (we'll call Jub) starts trying to defend him until he says "Jub I like your ass" and "I look at Jub and Kat ass." Yeah Jerry was kicked soon after. Jub tried to defend him but the rest of us agreed that he went way too far. Now fast forward to the next school year. Kat had left the school so now there's an open spot at our table for 4 (the rest of the group was spread throughout different classes). Jerry decides to take it. Here comes part two. We notice that Jerry tends to stare... In the wrong places. In a group of 80% girls this is a problem. On top of that he doesn't do his work (a problem for a group of people who do their work) and is a constant distraction. He also starts to be VERY annoying. He will constantly try to peek into others conversations, fake a throw or hit to you and swap pencils. All of us start to become very annoyed. Even Jub, who at first defended him wanted to cut him off. I wanted to give him one last chance however. So we kept him. Now here's the final straw. He starts to hangout with this group of boys we call "roaches." They are loud, disrespectful, and just all around annoying. So now, Jerry's attracting the wrong people over here and we're all over it. My two other friends in the class have already cut him off but I'm hesitant to. So, Jerry constantly is around me doing the same stuff. I've tried to subtly cut him off but he's too dense to realize the hints. He's also recently said things about my girlfriends ass and I didn't like that. 

Long story short: Am I the Asshole if I cut off a person who is a pervert, constantly being annoying and distracting, and said perveted things about my girlfriend?
