I posted something like what I'm about to say on Soyddit, funny enough.
Yes. They definitely exist. My roommate is one of them. His girlfriend looks like an average e-girl, but despite being pretty much a point above my PSL rating, dude is also 6'1. I'm also guessing his family might be rich though, because he has a full RGB computer setup with triple monitors and an expensive looking gaming chair. Plus, we live in the nicest dorm on campus. I'm just assuming shit at this point, but he seems to be an outlier.
Outliers can be due to status and money.
That said, outside of status and money, they are very, very rare. The premise of the [incel] blackpill is to outline the general norms which are omnipresent in relationships and in dating. The blackpill, like other social theories and laws, won't always be 100% absolute, but yet again, it outlines the general norm of how things really are. I have seen a couple other outliers on campus, but that's a couple (literally maybe like 10 or 11) on a campus of 30,000.
I also most commonly see outliers within older people, who are in their 40s-60s, and especially if I go to a Wal-Mart or something, there are lots of old, fatass ugly men with old, fatass ugly women. I personally don't think that counts though. Involuntary celibacy is most commonly a trait in men born from 1992 to 2003, as women our age are way shallower than they were many years ago. Plus, those men might've been good looking at some point, and said couples might have been married before I was even born. There's so many factors that play into it that IT's "Wal-Mart Theory" isn't exactly a good measure.
But I'm just talking about looksmatching here. Men dating up? Never happens at all. Besides in older couples, yet again, I have hardly EVER seen that in a younger couple. With couples my age in mind, I've seen that literally maybe like twice within the past five years. I don't consider 7/10 Chadlites dating 9/10 Stacies to count, either, as after 6/10, most Chadlites and Chads are just cookie cutters of each other with slightly alternating features. I'm talking shit like a 3/10 male dating like a 6/10 girl.
