I have an acquaintance who went to some cities in England for a while for work and he's back with lots of cringe

Ugh good lord the cringe. Suddenly he's telling me how he's not a chai person anymore because "white people they drink coffee". Um. Okay?? I had to struggle to keep myself from physically recoiling at his new-found pretentiousness. He showed me a video of himself dancing at a night club and um 😬 he was trying to flex on me by showing me all these white girls "throwing themselves" on him.
He got so annoyed with me being completely unfazed by his "impressive alpha male white chick magnet persona" that he even asked me "buildingadoor!!! I'm back from England after all these months and you won't even ask me what I did there???" because he was bursting with all these stories to tell me -- the brown girl who said "no" to his sexual advances.
He had many more stories to tell about white women just being desperate to get into HIS pants. He sounded like a teenage boy who had just discovered what a va.gina is. I'd have thought someone in their late twenties would be far more mature about sex, racial diversity and cultural differences than this. Oh good lord. So much cringe in one post. I apologize for this SW. I guess I'm off to play "would you do" with Johnny o to cleanse my palette.
