>>42240067I honestly do think this is it. My ex didn't grow up watching anime at all, and he played mostly games like GTA, racing games, or Valve stuff. He studied engineering, went to the gym and was already fit, always hung out with his friends, etc.
After those Uganda Knuckles videos he decided to try vrchat and to simplify the story a bit, he now pretends to be a loli all the time, added triggers to make his character blush, asks for headpats, even learned how to use blender to customize his lolis and would tell me stuff like "Look at my shoes, they're sooo cute! Ah, this skirt looks lovely with this shirt, hehe, if I sit you can see a bit of my bum! I look so cute <3". He also started watching a lot of anime. A LOT. All the moe ones with lolis and ecchi fanservice.
He got fat, stopped shaving, stopped studying, turned down a huge job opportunity, stopped seeing his friends, he basically became a living stereotype.
He now has weird Russian "friends" who ask him to do suggestive poses with them using his loli in game and he actually does it, says he's "their girl" but "haha only jokingly!".
