The Top Charming titty jiggler is supposed to grow breasts by vibrating them to stimulate the blood flow or something. I honestly don't know. What I do know is there's a 5:00 video after the jump that's half titty-twitchin' and half somebody pretending to be a scientist making up a bunch of bullshit about how it actually works. Which, SPOILER: it doesn't. As a man who tries to play with breasts as much as possible, no amount of shaking will make them grow. Two words: get her pregnant. Kidding, totally not worth it.
Hit the jump for 5:12 of boobie-bouncin' WTFery.
