Although "kiss" was another promising "K", I did that one last year.
Knockin' Boots Podcast. It's put out by IGN and Gamescoop; given that, plus the fact that "knockin' boots" is an euphemism for sex (I'm not sure who wouldn't know that, but consider yourself informed), and it's basically dating and romance advice for...er...nerds. Apparently they're often shy and not good with reading girls. Who knew? To be fair, there are quite a lot of emails from women as well, but I enjoy listening to them all. In fact, this podcast kept me entertained on a 3-day, 24 hour + ride across the U.S. I'm pretty sure I listened to about seventeen episodes, but I can't be sure.
And yes, before I get hate mail--hate comments?-- I'm completely aware that not all gamers are nerds, and not nerds are gamers.
My husband listens to the regular IGN Gamescoop podcasts (video gaming news, etc), and he informed me that KB started as a random, every-once-in-a-while episode. Listeners would email in with their dating or hook-up questions, and the hosts would answer them and give advice: good, bad, and hilarious. Those episodes got so popular that they started a whole new podcast just for the KB questions.
Questions range all over the romance spectrum. Frequent ones that come up include how to get out of the dreaded "friend-zone", i.e. when a girl you're attracted to thinks of you as a sexless friend, or worse, a brother; how to break up with someone you're no longer interested in; should I get a "gamer" girlfriend and is it as awesome as it seems like it would be; and how do I manage to have a threesome.
Not only is the podcast hilarious, but the guys (and occasional lady) who host it give pretty good advice. But I've been known to have conversations with my iPod when I don't agree with something they have to say. Call me up, guys. I'd love to be a guest host on Knockin' Boots!
One more thing... They've created a pretty good drink called the Rum Job. The origins of the drink's name can be found here (click if you dare, the explanation is NSFW), but it's 1 part Captain Morgans Original Rum (or Captain's Morgans, as Greg Miller often says) and 3 parts Orange Crush or other orange soda. Serve in a plastic cup with ice.
Check out their Facebook page, and remember: even gamers need love, too. And they make great husbands.
You can find the podcast on iTunes and, I'd guess, other podcasty places. Just Google it.
