I have a considerably expansive vocabulary, although I have somewhat poor social skills, or grammar skills when talking..or something. I don't know how you'd call it and I'm not going in detail about it. Anyway, most of my guy friends are pretty much on par with me, more or else. But I know some dumb girls. One girl I talk to regularly is smoking hot, but so, so stupid. 17 years old I think. Almost every time I have a conversation with her, I end up teaching her a new word. Like halfway through my sentence she goes, "what does that mean?". In example: she tells me she thinks her wrist is broken. I knew it wasn't, but I go on and ask her if the pain is excruciating. She responds with a confused "what's that mean?". Surprised she didn't know, I answer, "ummm, it's like beyond unbearable." Then she asked me what unbearable meant. That was the moment that sealed it in my mind.
Also, as far as intelligence in kids today, I had an ex girlfriend that stated that the Native Americans spoke English before the Europeans came to the Americas as if it were fact. All my friends and I stood back in awe.
