I've got a collection of random information in my brain that makes me an awesome Trivial Pursuit partner, but is completely useless when it comes to real world application. Like say, job applications. I thought I'd share some of this random crap with you in the form of another acronym-ific series. I give you - Word Origins from Left Field - that's right, the WOLF. Er... ignore the fact that the "from" doesn't fit.
So, it's Valentine's Day. Hooray.
Here's a little etymology for romantic souls. The phrase wear your heart on your sleeve commonly means someone who shows their affection for others openly, without shame or caginess. This likely comes from a tradition in the Middle Ages at jousting tournaments for knights to wear a ribbon, or color, on their sleeves to signify in which lady's name they were fighting.
But if you think about someone actually having an internal organ on their outsides, it's kind of a turn off.
