/soy/ - Soyjaks

So, my son (15M) and I (42F) recently found this site named the "soyjack party", and he has been yelling out random things or slang abnormally. I called him for dinner and he said: "You obsessed new soycacuh, I'm not going down for dinner!" This behavior was very alarming to me. I have never seen him like this. He was up until 4am on a voice chat call saying "Everyone in this thread is a "jartey" fail" and some VERY racial slurs. I also noted he said something along the lines of "obsessed shalalala". I told him to come to bed IMMEDIATELY, but being the stubborn son he is, he did not suffice.

He is also hanging up posters that say "JOIN THE SOYJACK PARTY!" with a bearded character that is wearing glasses blowing smoke out of a cigar, and what looks to be a green character on the side. I think this "soyjack party" is changing my son forever, he is just shouting out weird slang randomly. At a family gathering (birthday) he randomly yells "New soy caucus can't sing happy birthday! GEEEK!" My husband immediately ran up to him and said "Have you lost your mind boy?!? That is very inappropriate! What does that even mean??" I agreed silently. He has just been very crazy lately after finding this soyjack party.

One other crazy thing - I am going to be very light on this part, but I saw him looking at what seemed to be drawn porn of a girl named "Soytan". I knew it because of the filename he had. I took his laptop away and I think that's what striked the odd behavior for the last couple days. He cannot interact with anyone socially because of all the slang that he is using infected his brain - or at least that's what I think. I take everything very lightly in this house, because you never know what could go wrong. May I even say he was diagnosed with ADHD - as to why he can't focus in class. He even doodled what looked to be that guy from earlier on that poster he hung up which got him kicked out of class, but just out of the classroom for a while, not like expelled or kicked out of school. I am still mad at him.

I haven't resolved the problem since, I am going to need a lot of help. I think this website has scarred his everyday social life forever. He has never been like this, I tell you!

Thank you for your time reading.
