From the Glossary To The Life of Highlyeccentric

Diversion: The opposite of a wingman. A wingman is a member of the same sex who enables you to pick up; a wingman/woman can also be a member of the opposite sex, such as a cousin, sibling, or obviously platonic friend, who will ingratiate you with other members of the opposite sex. A Diversion is a member of the (usually) opposite sex who will do you a favour by discouraging people from hitting on you and/or noticing your attraction to a third party. A Diversion does not have to know about their role- you may cultivate the illusion of a lingering attraction to them; if you are normally affectionate with them you can strategically hug/massage/joke/etc with them in the presence of unwanted suitors. However, a Diversion who knows you don't want to be picked up will conveniently appear at intervals to speak with you, hug you, warn you that you're not doing your own cause any good by flirting with the unwanted suitor.

everyone needs a good Diversion

Why Anglo-Saxon Literature Is Important to Modern Politics

Because it will allow you to draw shaky analogies which will then be criticised by medievalists

Forget Sex. It's all about medieval underpants

Someone presented a very august paper at Leeds, and the bloggers have run away with it, and now our modern literate culture is all based on underpants.

Check it out at Got Medieval 
It's not as if there were piles of soiled underwear lying around the towns of medieval Europe, covering all the available surfaces, thoroughly stinking up the place, until someone finally said, "I know, we'll make paper out of them, that'll solve that problem," and then with all the paper lying around, people started reading and writing out of self defense. Then, bam, we had ourselves a Renaissance in celebration.

And also at Unlocked Wordhoard
I want to suggest that the rise of underpants wearing was driven by a market in used underwear, so that the medieval person could say, "well, I'll invest in this underwear because I know I'll be able to recoup a small part of that investment later when I sell it to be made into books."

Yes, that the new meme! Increased literacy caused people to wear underpants, not visa-versa! And I already have proof: Paris Hilton, known non-underwearer, is also not a very literate person. I, on the other hand, read a great deal, and I wear underpants every day. Indeed, when my children were illiterate, they wore diapers, not underpants, but now that they are literate, they wear underpants.
