Quite simply a giant douche bag. More often than not, a Lacrosse player and/or some form of Jock. A male who is either obsessed with his own stomach or wants everyone to see his stomach for some unknown reason. (it most certainly doesn't have a bad itch) This male is either looking for envy among other males, to signal other belly scratchers of being part of the club, or the possibility of female attention. Look for scratching sessions anywhere from 10-15 seconds to a full 4 minutes depending on location.
Side effects of talking to belly scratchers will cause a severe loss in brain cells. Avoid as much as possible.
A simple crack with no literal definition, it's merits are only how funny and stupid it sounds. And there is no comeback after you have been called an African Bootyscratcher, just walk away and live another day.

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
