Here's the bottom line from the Assapprasier.  We back porch afficionados want a "butt" rating in the general review page.  You tittie boys get plenty of info on size and shape but what about the some acknowlegment on the junk in the trunk for us bottom dwellers.  Don't we have feelings too?  Don't we have rights?

I'm tired of being ignored.  I'm calling for the silent assjority to rise up from between the cheeks and demand our rights as equal citizens.  This type of thing would never happen on my home planet of uranus.

And guys, when you give your detailed descriptions, please give a little info on the back hills.  A little mention of shape and size would really be asspreciated.

Size, shape, resiliency, responsiveness.  Is the button right there to press, or do you have to drill deep?  Ample area to spank, and how indeed does the handprint look?  Sensitive to touch?  Goosebumps?  And what of the golden fold between buttock and thigh?  

All questions that this hobbyist, and I'm sure many others, want answered.

Poetry, Turk...poetry.  It makes me weep.

He's from Uranus.   lol   I vote with you brother. Lets add the Tushy factor!!

databases are rather prosaically literal beasts.  Just how do we parameterize this?

Rear End:
   1 - Dead Man's Curve
   2 - Skin and bones
   3 - Scraggly
   4 - Flaccid
   5 - It'll pass
   6 - Reachin' for the foothills
   7 - Lots of cushion for pushin'
   8 - Curvaceous
   9 - Venus di Milo Would be Proud
  10 - Mountain heaven

The tittie folks have a big advantage here in that the objects of *their* devotion can be neatly (and even somewhat objectively) parameterized by two numerical measurements:  bust and cup size.  So, who wants to start developing the 'TER Standard Scale of Bum Perfection [tm]'?

Cheers!

describe how large her rear end is without making value judgements about whether large or small is better.

No need for a numeric scale, just as there is no numeric scale now for "Build".

Just informative, so the client can make an informed choice.

Everyone has a different definition of "great" when it comes to buns.  An objective description without value judgements is essential.  

Also, when you get to the larger sizes there's a big difference between J-Lo and Jello and the description needs to account for that.  Is it large-but-in-charge or The Blob! Of course, these are all medical terms.

How about just using comparative analysis based on some known asses, such as:

J-Lo
Beyonce
Britney Spears
Roseanne Barr
Carmen Electra
Pam Anderson
Rosie O Donnell
Twiggy

11. Pancake-Flat as one

I thinks its a good idea, big butts do litle for me, now a small round tight ass will give ame a woodie hard enough to bust a zipper.

A thin waist slowly expanding into a set of wide hips that frame a nice round ass that has cheeks whose shape can be seen through any type of clothing.  OK, now I am creamy hot.
