First off, his medallion is turned around backwards, so he's lying throughout this video.
Second of all, it's finally hitting him how jacked up his life is and how no one wants anything to do with him. He thought he could just wave away all the bad and obnoxious shit he's done and that he'd be welcomed by the brony crowd or other personalities he desperately wants to be part of. Chris is literally realizing just how alone he is. Something is definitely going on where someone kicked him to the curb (Flutter?) or else he tried to get in with the brony people he's stalking who finally told him off in terms that he could understand.
"Betrayal" to Chris means that he wants to be friends with someone (or wants to fuck them), is "nice" to them, but then they don't want to have him around or interact with him in any way. He still thinks as long as he marks off a checklist of what "friends" are supposed to do, as in "I'm nice, you like nice people, so why aren't you my friend? I'm nice!", then said person should automatically be pals with him. He still doesn't understand that's not how it works. He still is in his "dating ED" mindset where as long as you complete various steps, you should get the reward. He still doesn't understand empathy or why people despise him.
