We previously asked you to help us figure out if Sticky Sweetie's bubblegum-and-glue fetish videos were porn. Well, the votes are in and it turns out that 50 percent of you think the Web fetish channel is porn and 50 percent of you think it's not. So, thanks for nothing -- now we're more confused than ever.

Luckily, from the sweaty nether regions of the Internet comes a new phenomenon to simultaneously frighten and titillate us. A murky cross between Internet meme and fetish video, boob punching -- aka boobie boxing, aka breast fighting, aka jug handling -- is increasingly popular on YouTube, with a search bringing up over 400 results.

The videos range from playful slaps between giggling friends to solo boxing matches in the dark. Some of the vids seem to be aiming simply for surprise comedic value like that of an unexpected nut shot, and we think it's high time that women were liberated to participate in "Jackass"-style stunts. But some of the videos have a more lascivious tint. What is it about girls in their underwear smacking each other's funbags that makes us feel kind of funny?
