YTA. Grow up and tell Oliver to his face that he’s not invited. Also, this is Bored Panda. You seem to have mistaken it for Reddit.

YTA. You and your friends could have taken the energy y'all put forth in the "clever" thing y'all did in the theater into telling him to stop talking with food in his mouth. Show him the bits and pieces of food right then and there; he wouldn't be able to deny it and he'll also see what he's doing. If he continues, then tell him you can't do this anymore and leave. You could have also taken the energy you used to post this online to tell Oliver you're sorry for how you went about things, but you have something that he needs to know. Again, if he doesn't change, then stop hanging out with him. You're not asking him to change his personality, just improve his manners. That's what a true friend would do. You seem irritated, but you are a bad friend looking for the support of complete strangers to treat someone badly instead of growing a pair (of balls or of ovaries) and helping your friend become aware of how gross they are presenting themselves when the talk with food in their mouths.

YTA for not being honest and learning to say: No. I get it, you don't like Oliver. And that's fine. But then don't give in to 'keep the peace'. That's just disgusting. Stand up, be an adult and say: No. Hey, my internet is down, you should buy my ticket. No, I won't. It's that simple. You don't have to argue. Whatever he throws at you, all you have to say is: "no, I will not." Or: "No, I don't have to do that." And as hard as it is, if he asks why, tell him the truth: I won't buy your ticket because A: you never pay it back and B: you're a liar. If you had no internet, you couldn't even write me. Also C: I do not want you to come with us because you spit on my snacks and ate annoying. But you string him along and enable him, and that's why YTA. You deserve all the misery he brings you, because you xou don't tell him to stop and don't say no although you could. No one forces you to go along. He's not a rapist with a knife or another kind of offender who has power over you. You're just a doormat who can't say no.

It's nice that you are now making your own articles, BP, but this formatting is awful to read

The "protagonist" of this story should have just told Oliver, directly and sincerely, that his behavior was bothering them, instead of lying and then covertly sneaking away (which sounds like a very childish thing to do). So this is a definitive "YTA."

Yta.. so instead of talking to this guy you abandoned him when he thought he was with friends.. I would rather be told I spit when I talk, eat, laugh etc.. then to be ditched when out with "friends"...

YTA and a terrible friend. If you are friends like you said, just talk to him (one on one, not in a group). If he doesn't put in an effort to not spray chewed up food at you then I suggest re-evaluating your friendship.
