I remember the exact moment when I stopped liking Friends. In TOW Chandler takes a bath, Monica spends time encouraging him to take a bath, something considered 'feminine' (because bathing and smelling good are gendered, apparently?). Anyway, as soon as he does, she calls him a 'girl in a tub'.
Using 'girl' as an insult is bad, but it's worse when it comes from a woman, and worse again when it's from the woman who was telling you that having a bath is a relaxing thing.
Having said that, the only thing that kept me watching through the last few seasons was Monica and Chandler's relationship. It was refreshing to me to see a couple that didn't low-key hate each other all the time.
