Wednesday WOLF - Jump the Gun

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.

Jump the gun is a phrase I use often, partly because of my environment, and partly because I'm always in a hurry and slightly spastic. But where does it come from?

After I looked it up I was kind of ashamed that I didn't figure it out on my own. Jump the gun, not surprisingly, comes from track and field events where the participants leave the starting line before the official has fired the gun to being the race.
