I don't think that's it. I think people just enjoy seeing conceited people get humbled. So let's say a woman calls up, says she has 2 kids, rates herself a 6 in the face, and weighs 280... ok whatever, do you. But if she follows that up by saying a man making $50k/year is below her, and she can't date down like that... it's entertaining to see her humbled. Because what's she have going on to talk down on people like that?
Sports Example:
You have the Panthers up there so I assume you watch football. Let's say you're playing the Chargers one week... you probably don't care about Mike Williams individually... you just want to win. BUT if during the week Williams is like "With the bum DB's the Panthers have, I may put up 300 yards and 5 TD's on Sunday" you're gonna want to see him humbled on Sunday. Especially since Williams isn't a pro bowl or all pro player and he's talkin that kinda shit.
