Slendertone Will Make You Blow.

Check out "First Time," the first-ever online video attempt by a company called Slendertone.

Put together by Publicis, the video depicts individuals, couples and groups either grinning or standing around uncertainly -- before their faces explode with either alarmed or joygasmic expressions.

The ad leaves you to guess what Slendertone actually does, but especially curious users are invited to visit slendertone.com, where all is revealed.*

Until you actually go out of your way to do that, however, you'll probably be standing around going, "It's a vibrator, right? Or an orgy-inducing party game?"

Probably doesn't help that at some point, the feel-good background song exclaims, "I'm about to blow, yeah!"

*Too lazy to put those typing fingers to good use? That's cool, here's help: Slendertone is some kind of magic belt for chunky areas on your tummy, legs or arms. I guess it vibrates or something while you wear it in order to tighten and tone you.
