An advertising catchphrase made famous by Nike. I suspect it has its malevolent qualities to those who manufacture Nike product, like the workers at the Lotus Footwear sweatshop in the Philippines. Just do it. And when some of them got fired and weren't given their severance pay, they protested and got their asses kicked by police and security guards, always ready to lend a hand, a fist, a baton, and a rifle to their American friends. Just do it.

Thwack!
