In the season 6, episode “Pick-a-Little, Talk-a-Little” of Sex and the City Carrie, Charlotte, Samantha, and Miranda do something they rarely consider: seek dating advice from a man. When no-fuss Miranda can't comprehend why the man she went on a promising date with wasn't calling her, Carrie's boyfriend Berger spells it out. "He's just not that into you,” he says. Miranda’s relieved to hear something so simple—liberated from weeks of hand-wringing by the phone—while her cosmopolitan-sipping friends are flummoxed. The sentiment quickly reverberated across America's single women.
The revelation on the 2003 episode was the brainchild of Liz Tuccillo and Greg Behrendt, who were writers on the hit HBO show. The two stumbled onto the concept in the writers’ room when a colleague was asking for advice on why she hadn’t heard from a recent date. The show’s resident cisgender, straight male writer, Behrendt, said the now iconic line—leading to shockwaves and debate among their coworkers, and ultimately the creation of the SATC bit. It eventually inspired him and Tuccillo to write He’s Just Not That Into You, the 2004 no-bullshit dating manual that sparked a revolution of boundaries and breakups.
