At the height of Spice Girls fever, the British band's "girl power" slogan was sometimes cast off as a shallow marketing tactic designed to sell CDs (remember them?)

But the musicians' message was real, and this new slice of spice proves it. The girls were captured on film back in 1997, berating a male crew member who demanded the band show more cleavage during an advertisement for Polaroid.

"Why did you ask that? To have our cleavage showing and our midriff showing," Melanie Brown asked the unnamed male crew member.

"It's every male's fantasy," the man replied. "Well you can f*ck off," Brown fired back.

The video was originally posted in May by director Mackenzie Rough, but an edited version has recently gone viral on Twitter. It's a glorious watch.

"You chauvinistic pig. That's such an easy cop out," Geri Halliwell angrily told the cocky man, as Victoria Beckham takes his sunglasses off his head and tries to sell them.

"At your age, you should know better by now. You're in advertising," Halliwell added, as the man nervously tries to defend what he said.

At the end of the video, Brown and Halliwell sarcastically congratulates the man who caused the commotion.

"And we especially thank you, because he's the one who said can you show a bit of cleavage and midriff. And we said no, girl power!" Brown told the camera.

Bring back the '90s.
