Playboy, an unlikely ally in women’s quest to end street harassment, especially because they’ve made millions and millions off encouraging men to ogle at women, has done something wonderfully feminist. Hugh Hefner has even claimed we are living in a post-feminist world before, meaning that a chart like this shouldn’t even be necessary. But here we, feminists, are in agreement with Playboy’s work for once. Hell just froze over.

Playboy and graphic designer Shea Strauss have designed an excellent explanatory flowchart (click to see full chart) that answers when it’s okay to catcall a woman. In a sort of choose-your-own adventure game, guys can follow the line that represents his libido and male entitlement the best with options like, “Are you sexually frustrated?” if yes, proceed to “Yeah, I wanna yell sex stuff at people.” It eventually all flows down to “Nope, don’t do it,” and “Yeah, go for it.” There’s a real educative twist to help folks understand that the only case where it’s okay to catcall is when there’s mutual consent (and even then they make clear heckling is an equal opportunity for both sexes) and when it’s an actually kitty. For everyone other instance, it’s not cool.

This chart comes in the wake of other great devices to battle street harassment. There’s the bell Hooks hotline, which provides women a fake number to give to strangers who ask for it. The idea (unfortunately, this reasoning exists) is to safeguard women “because we’re [women] raised to know it’s safer to give a fake phone number than to directly reject an aggressive guy.”

There’s also the Cards Against Harassment, which are business cards that anyone can get and hand out to street harassers to explain how their actions negatively affect women. And Tatyana Fazlalizadeh’s art project, Stop Telling Women to Smile attempts to combat harassment directly on the streets too.

While this great flowchart doesn’t get Playboy out of the doghouse for its years of misogyny, objectification, exploitation and body issues, it is certainly a step in the right direction.
