Classic copypastas

My son (14) watches a lot of video game streamers on Twitch.tv. I personally don't find them entertaining but I can understand why some people (like my son) do. Over the past month he's starting using terms like "pog", "jabaited", and "Kappa" which I guess are terms that are used in the scope of Twitch. I don't have an issue with my son using these terms but it's gotten to the point where every sentence is Twitchspeak. We were having dinner and my daughter (age 12) was talking about how she got accepted for a summer program with the local animal shelter, and my son said "Pog you, easy clap". I told him that it was getting out of hand and that he would have to communicate normally to his parents and family. To that he said "Weird champ, feels weird man, normies omega LOL." Until he learns to communicate like a normal human being I've blacklisted Twitch from the internet for the time being. He's hysterical now but I told him that I would unblacklist it if he stopped using twitchspeak, but he's refusing to stop so for now it's banned. AITA?

What the fuck did you just fucking say about me, you little bitch? I'll have you know I graduated top of my class in the Navy Seals, and I've been involved in numerous secret raids on Al-Quaeda, and I have over 300 confirmed kills. I am trained in gorilla warfare and I'm the top sniper in the entire US armed forces. You are nothing to me but just another target. I will wipe you the fuck out with precision the likes of which has never been seen before on this Earth, mark my fucking words. You think you can get away with saying that shit to me over the Internet? Think again, fucker. As we speak I am contacting my secret network of spies across the USA and your IP is being traced right now so you better prepare for the storm, maggot. The storm that wipes out the pathetic little thing you call your life. You're fucking dead, kid. I can be anywhere, anytime, and I can kill you in over seven hundred ways, and that's just with my bare hands. Not only am I extensively trained in unarmed combat, but I have access to the entire arsenal of the United States Marine Corps and I will use it to its full extent to wipe your miserable ass off the face of the continent, you little shit. If only you could have known what unholy retribution your little "clever" comment was about to bring down upon you, maybe you would have held your fucking tongue. But you couldn't, you didn't, and now you're paying the price, you goddamn idiot. I will shit fury all over you and you will drown in it. You're fucking dead, kiddo.
