The whole thread is great, like an incel weirdo that totally didn't get what the show is about watching to the very end. At one point he said that cringe comedy is a contradictory term, even thought he literally watched the series finale of cringe comedy the show.
Me too, though I'm not actually familiar with Peep Show at all. I think the Borat "style" is to combine cringe humor with an attempt to see how much of a fool you can make of normal people. Like how ridiculous the things you can get them to say / agree to are. In Borat it was more just providing a platform for them to say the dumb shit they already felt, in Nathan For You it's more about pushing the limits of the dumb shit they'll just go along with if you bring it up first, but it hits the same notes for me.
