Fennell started writing after thinking over all the conversations she’d participated in about alcohol and consent — all the rollicking stories guys told about hitting on drunken girls, or getting them drunk to “loosen them up.” None of this was taboo when she was younger: “It was all completely normalized by all the American ‘raunch era’ films and TV that everyone watched,” she told me. “Drinking was part of seduction culture — and if people couldn’t remember things, it was often met with an eye roll.” Fennell questioned that logic. If having sex with a girl who was blackout drunk was nothing to feel bad about, then a man wouldn’t feel guilty if she turned out not to be drunk, would he? It made her wonder. “What if I went to a nightclub and pretended to be really, really drunk, and somebody took me home, and then just as they were removing my pants, I revealed I wasn’t drunk?” An image formed in her mind of a woman sitting up in bed, suddenly sober, and asking, “What are you doing?” She later described this very scenario to a producer. “I said, ‘And then she sits up, and she’s not drunk!’ And he went, ‘Holy [expletive], she’s a psycho!’”
