It means Whippersnapper!
Ok it really means: an impertinent, presumptuous person, especially a youngman. But it just cracked me up that the definition says "whippersnapper"
While it originally came from Jack of Naples, it later was attributed to the badge of someone other another 600 years ago because they used a monkey's leash on their badge!
Life really is just one big old game of post office when you think about it.
